The Stonehenge Transportation Mystery

Introduction

Exploring the origins and transport of the stones used to construct Stonehenge remains a fascinating subject, rife with theories and controversies. The viral interest generated by my blog post this week, which highlighted a map showing three known sites of the stones’ origins, barely scratches the surface of this complex logistical puzzle. Indeed, there are stones from even greater distances, raising myriad questions about how these megaliths were transported to their final resting place at Stonehenge. This essay aims to delve into these logistics, providing a comprehensive overview grounded in the latest research and theories. (The Stonehenge Transportation Mystery)

The Bluestones

Recent advancements in micro-spectrum analysis have significantly contributed to our understanding of the origins of bluestones. However, this is not an exact science, as the movement of rocks due to glacial activity and post-ice age water flows complicates their traceability. Some academics have proposed that the bluestones found at Stonehenge were not quarried and transported from Wales but deposited nearby by glacial action. This theory, however, conflicts with geological evidence indicating that the last ice age glaciers did not reach as far as Stonehenge, stopping instead at the Bristol Channel. This discrepancy casts doubt on the glacier transport theory, suggesting the need to consider earlier ice ages, such as the Anglian, which occurred over 500,000 years ago. Yet the immense timescale involved means that any stones moved by such glaciers would be deeply buried beneath millennia of soil, making their discovery improbable.

Furthermore, the lack of bluestone erratics in the vicinity of Stonehenge further challenges the idea of glacial transport. The site at Craig Rhos-Y-Felin, identified as a source of the bluestones, shows clear evidence of human quarrying activity, contradicting the theory that these stones were randomly picked up from glacial deposits. The discovery of human hearths and quarrying tools at Craig Rhos-Y-Felin, along with a partially quarried bluestone, strongly suggests that these stones were intentionally selected and transported for use at Stonehenge.

Craig Rhos-y-felin to Stonehenge
The overland path from Craig Rhos-y-felin to Stonehenge is insane. It goes from 75m OD to 541 OD and crosses 95 valleys – the idea that you can either roll, drag or ox-cart such a route without a road is bonkers!!

The Sarsen Stones

The origin and transportation of the sarsen stones present a different set of challenges. These stones are found scattered across the Salisbury Plain and further afield, in areas never reached by the ice sheets that covered Britain during the last ice age. The popular theory that the sarsen stones came from West Woods near Avebury suggests that they could have been dragged to their current location. However, recent observations indicate that many of these stones are in paleochannel riverbeds rather than rock outcrops. This suggests that they were transported by ice-age floodwaters rather than being quarried from nearby outcrops.

West Woods to Stonehenge
Even the shortest route known to transport these stones is difficult to follow, as the 12 valleys and 14 peaks shown on this map testify.

Theories of Transportation

The theory that the stones could have been moved over frozen rivers during the ice age is intriguing but fraught with logistical issues. The absence of a significant human population capable of organising such an endeavour, coupled with the challenges of moving heavy stones over potentially thin ice, makes this theory less plausible. Additionally, the radiocarbon dating of Stonehenge would be significantly off if the stones had been transported at the end of the ice age.

LiDAR, or Light Detection and Ranging, is a remote sensing technology that uses laser light to densely sample the earth’s surface, creating highly accurate topographic maps. It has revolutionised archaeological surveys by uncovering features difficult or impossible to see from the ground or through traditional surveying methods. Regarding Stonehenge and the transportation of the stones used in its construction, LiDAR technology offers invaluable insights into the landscape and potential transport routes used by ancient peoples.

Ditching to Stonehenge
The trilithon stones, weighing around 50 tonnes, reportedly come from Sussex. Such weights were successfully transported down the Nile on boats.

LiDAR Evidence and Stonehenge

LiDAR has been instrumental in mapping the landscape around Stonehenge, revealing details that have remained hidden for millennia under vegetation or soil. This technology has the potential to identify old riverbeds, trackways, and other features that could suggest routes for transporting the massive sarsen stones and bluestones used in the monument’s construction. However, despite its capabilities, LiDAR has not yet provided definitive evidence of prehistoric roads or paths leading directly from the quarries to Stonehenge.

Key Findings from LiDAR Surveys

No Prehistoric Roads from Quarries: LiDAR surveys have not found any evidence of engineered roads or paths originating from the bluestone quarries in Wales or from locations where sarsen stones are found. This absence challenges theories that rely on overland transport of the stones using rollers, sledges, or ox-carts over vast distances and rugged terrain.

Ancient Waterways and Paleochannels: One significant contribution of LiDAR is the identification of ancient waterways and paleochannels. These features are crucial for understanding the prehistoric landscape, suggesting that rivers and watercourses may have played a significant role in transporting the stones. The larger rivers identified by LiDAR, which were navigable in the past, support the theory that water transport was a feasible and preferred method for moving the stones.

Atkinson's Method
Atkinson proved with just four small schoolboys that a 4-tonne stone can easily be moved by boat down to the River Avon

Landscape Features: LiDAR has revealed the complexity of the landscape through which any transportation route would have had to navigate, including valleys, dense forests, and waterlogged areas. This detailed mapping underscores the logistical challenges faced by ancient builders, further calling into question the practicality of relying solely on land-based transport methods.

The Stonehenge Transportation Mystery
We have now found empirical evidence of boat yards in which catamaran design is made to carry large weights in Wales, dating back to the Bronze Age and beyond

Implications of LiDAR Evidence

The evidence from LiDAR surveys, particularly the absence of prehistoric roads and the emphasis on natural watercourses, suggests a reevaluation of how the stones were transported to Stonehenge. The lack of direct routes from quarries to the site and the identification of navigable ancient rivers and paleochannels lend weight to theories prioritising water transport. This perspective aligns with the understanding that ancient peoples were highly adept at utilising their natural environment to achieve monumental feats of construction.

Alter Stone to Stonehenge
The Altar Stone is now suspected of coming from as far as Scotland, as its Geo signature is not available down south (I would guess Doggerland for obvious reasons), but even if it just came from the Yorkshire Dales, the idea of l, and transportation is pure nonsense

Short Transportation systems from the boat harbours to the Monument

Mechanical Advantage of Poles (from the book – Dawn of the Lost Civilisation)

The principle of leverage, applied through poles, provides a mechanical advantage when handling heavy weights. Professor John Cunningham, an art professor at Skidmore College, has introduced a novel concept, creating a new class of simple machines based on flexible rods. Unlike traditional machines, Cunningham’s design not only multiplies force but also distributes it and stores mechanical energy.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

Consider a scenario with a 20,000-pound stone. If you attempt to support it on two rigid beams, each will bear half the weight (10,000 pounds), posing a risk of fracture. Now, imagine spreading the load across 20 solid, parallel beams, each supporting only a fraction of the total weight, making the burden manageable. Cunningham’s innovation takes this idea further by replacing solid beams with flexible poles.

Stone Transportation and Dumb Censorship
The Bluestones were carried, not dragged, to Stonehenge

In the flexible pole structure, each pole can be raised independently without affecting the others. By lifting one end of a pole, a small amount of extra energy is imparted to that pole, and the energy is distributed across the structure. The weight rises by a fraction of the raised end, divided by the number of pole ends. If one end is lifted by a foot, the weight on each of the other pole ends diminishes by a corresponding fraction. Using this method, heavy loads can be lifted with significantly fewer people, as each person is only moving a fraction of the weight at a time.

This innovative approach enables efficient handling of substantial weights, offering a unique perspective on the use of mechanical advantage in lifting and distributing loads. (Stone transportation and censorship)

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

Cunningham has distilled the concept to a formula:
D = S x 1/N

Where D is the distance, the load is raised, s is the distance any one pole is blocked up, and N is the total number of pole ends in the system. Given n is the number of pole ends lifted simultaneously, the mechanical advantage for any symmetrical pole configuration will be N/n.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery


So, the fact that a pole bends like a bow, storing energy, makes it easier to carry. So easy in fact, that it acts as a lever and gives you a mechanical advantage. This principle would be well known as it is the same principle as how a bow works as it is a store of potential energy, you can’t throw an arrow 100 metres, but the bowing of the wood channelled through a small area (the string) give you the potential energy.

Walk like an Egyptian

The experiment showed that 48 students ( four x 12 poles) could lift 2.3 tonnes, which was the weight of one of the pyramid’s building stones. The larger the stone, the more poles and men you need, but it was quite easy even for wimpish students. In prehistoric Days with Cro-Magnon works you would need only 24 people to move a Pyramid stone or a Bluestone at Stonehenge without the rest blocks the video has included in their H & S safety assessment….LOL!!

A-Frames and Cranes

The advancement of technology and the movement of massive stones, such as the Sarsen stones at Stonehenge, Avebury, and Carnac, demand a closer examination of the engineering and logistical challenges faced by the ancient civilisation of Homo Superior, also known as Cro-Magnons. The Sarsen stones, weighing up to 60 tonnes, were not merely transported but meticulously erected, presenting a feat that even modern attempts struggle to replicate.


In our exploration of ancient technology, we encounter the question of how to transport and handle colossal loads. The Sarsen stones serve as an illustrative example due to their significant size, and it is perplexing that historians and archaeologists often overlook the intricacies of moving and placing these stones. This oversight persists even though, even with today’s technology, replicating the achievements of Homo Superior at Stonehenge remains a daunting challenge.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery


The crane, a machine designed to lift and move heavy materials, is pivotal in the transport and construction industries. Equipped with a hoist, wire ropes or chains, and sheaves, a crane utilises mechanical advantages to lift and lower materials beyond the capacity of human effort. Historically, the invention of the crane is attributed to the Ancient Greeks in the late 6th century BC, as evidenced by cuttings for lifting tongs and Lewis irons on stone blocks of Greek temples dating to around 515 BC.

However, when scrutinising Stonehenge, we encounter a fascinating divergence. In contrast, archaeological evidence points to the use of lifting devices, particularly with cuttings indicating the application of cranes, the peculiarities of Stonehenge’s construction challenge conventional narratives. Notably, the placement of lintels on Sarsen uprights and the presence of holes like Y & Z, potentially serving as foundations for A-frame crane legs, hint at a more sophisticated lifting apparatus.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

The reluctance of some scholars to acknowledge advanced lifting devices in the historical context of Homo Superior may stem from the challenge they pose to established historical frameworks. Nevertheless, the investigation into the engineering marvels of Stonehenge encourages us to reassess the capabilities of this ancient civilisation, prompting a deeper understanding of their technological prowess and organisational acumen.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

The transition from ramps to the more sophisticated winch-and-pulley hoist marked a significant shift in ancient construction technology. The emergence of the compound pulley system, attributed to Aristotle in the Mechanical Problems, coincided with a notable decrease in the weights of stones handled on Greek building sites. This transformative period saw the prevalence of smaller stones, weighing less than 15–20 metric tonnes, in contrast to the archaic era’s trend of using larger blocks.

The adoption of the crane, facilitated by the compound pulley system, introduced a more efficient and practical method of vertical motion. Grecian temples of the classical age, exemplified by the Parthenon, favoured using several smaller stones rather than fewer larger ones. Monolithic columns, a prominent feature in earlier constructions, were gradually replaced by multiple-column drums.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

The reasons behind this technological evolution are not entirely clear. It raises intriguing questions about whether the shift from larger to smaller stones was due to the loss of past techniques, improved quarrying methods that enabled faster cutting of shorter blocks, or other factors influencing construction practices. The shift in societal dynamics, with smaller, professional construction teams being favoured over larger bodies of unskilled labour, is proposed as a potential contributing factor. The crane, with its efficiency in handling smaller stones, became preferable in the more volatile social and political conditions of ancient Greece.

While the exact circumstances of this transition remain uncertain, the historical record indicates that the compound pulley system and the crane became integral to Greek construction sites. The literary evidence from Aristotle’s Mechanical Problems and the resurgence of larger block sizes at Greek temples suggests a correlation between the adoption of the compound pulley and advancements in construction techniques. The earliest construction cranes, likely powered by humans or beasts of burden like donkeys, marked a transformative period in ancient construction methods.

(Stone transportation and censorship)
The Stonehenge Transportation Mystery

The evolution of cranes played a crucial role in the construction of tall buildings, enabling the lifting of heavier loads. In the High Middle Ages, harbour cranes emerged to facilitate ship loading and unloading, often integrated into stone towers for enhanced strength and stability. The earliest cranes were crafted from wood, but with the advent of the Industrial Revolution, materials like cast iron and steel became predominant.

At Stonehenge, the construction methods are a subject of speculation, with suggestions that timber A-frames were employed to raise the stones. Teams of individuals may have hauled the stones upright using ropes, and the topmost stones (lintels) could have been incrementally raised on timber platforms and slid or pushed into place. Carpentry-type joints on the stones indicate a high level of woodworking skill among the builders.

The Stonehenge Transportation Mystery
The Stonehenge Transportation Mystery

The idea of A-frames finds support in demonstrations by individuals such as Wally Wallington, a retired construction worker, who showcased techniques based on lever principles for rotating, lifting, and positioning heavy monoliths. An A-frame, essentially a basic crane without a pulley or winch, operates on similar principles to facilitate vertical movement. Adding a swivel base could transform it into a fully functional crane, a concept compatible with the mortise-and-tenon joints observed at Stonehenge.

(Stone transportation and censorship)
The Stonehenge Transportation Mystery

Estimates of the manpower required for Stonehenge’s construction suggest a substantial effort, with millions of hours of work. The various phases of Stonehenge’s construction, from the initial to the third phase, may have required extensive human labour, amounting to up to 20 million hours spent working the stones. The primitive tools available at the time necessitated considerable effort, highlighting the strong will and advanced social organisation required to build and maintain such a monumental site. Stonehenge stands as a testament to the ingenuity and determination of its ancient builders. (Stone transportation and censorship)

Robert John Langdon, a polymathic luminary, emerges as a writer, historian, and eminent specialist in LiDAR Landscape Archaeology.

His intellectual voyage has been interwoven with stints as an astute scrutineer in government and grand corporate bastions, a tapestry spanning British Telecommunications, Cable and Wireless, British Gas, and the esteemed University of London.

A decade hence, Robert’s transition into retirement unfurled a chapter of insatiable curiosity. This phase saw him immerse himself in Politics, Archaeology, Philosophy, and the enigmatic realm of Quantum Mechanics. His academic odyssey traversed the venerable corridors of knowledge hubs such as the Museum of London, University College London, Birkbeck College, The City Literature Institute, and Chichester University.

In the symphony of his life, Robert is a custodian of three progeny and a pair of cherished grandchildren. His sanctuary lies ensconced in the embrace of West Wales, where he inhabits an isolated cottage, its windows framing a vista of the boundless sea – a retreat from the scrutinising gaze of Her Majesty’s Revenue and Customs, an amiable clandestinity in the lap of nature.

Exploring Prehistoric Britain: A Journey Through Time

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives grounded in cutting-edge research, particularly LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualises my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts, are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp receive re-evaluations based on LiDAR analysis in my posts “Lidar Investigation Cissbury Ring through time” and “Lidar Investigation White Sheet Camp,“ revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts, including Car Dyke – ABC News Podcast and Lidar Investigation Car Dyke – North Section, which suggest a Mesolithic origin 2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis, which has helped explain landscape transformations over time. I have discussed this hypothesis in several posts, including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes astronomical insights into ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.

The Stonehenge Crescent: A Monument to a Lost World

A Monument to the Dead — Not the Sun

One of the most recognisable images in archaeology is that of a perfect circular Stonehenge — a continuous ring of upright stones capped with lintels. (The Stonehenge Crescent: A Monument to a Lost World)

You’ve seen it everywhere:

  • Textbooks
  • Reconstructions
  • Documentaries

It has become the accepted version of the monument.

There is just one problem.

Stonehenge was never built that way.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Myth of the Perfect Circle

The circular Stonehenge exists more in illustration than in reality.

When we examine the monument itself, the physical evidence tells a very different story:

  • Several stones required to complete the circle are missing
  • Others are too small to support lintels
  • Some are incorrectly positioned for a continuous ring
  • Stone holes reveal uprights that do not conform to a circular design

This creates a fundamental contradiction.

If Stonehenge was intended to be a perfect solar temple, then:

  1. It was never completed
  2. Or it was deliberately dismantled

Both explanations are unsatisfactory.

There is a far simpler solution.

It was never meant to be a complete circle.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

Structural Proof: Stone 11 Breaks the Model

This conclusion is not just interpretive — it is structural.

One stone alone exposes the flaw in the circular theory.

Stone 11.

This stone is:

  • Smaller than its neighbours
  • Structurally inadequate
  • Incapable of supporting a lintel

This is critical.

A continuous lintel ring requires every upright to meet a basic engineering condition:

It must support load.

Stone 11 cannot.

This is not a minor anomaly. It is a mechanical failure within the supposed design.

There are only two possible explanations:

  • The builders made a fundamental structural mistake
  • The circle was never intended to be continuous

Given the precision elsewhere in the monument, the first option is highly unlikely.

Which leaves only one conclusion:

Stone 11 is not an error — it is evidence.

It proves that the monument was never designed as a complete ring.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Different Shape Emerges

When we examine all surviving stones and stone holes together, a new pattern appears.

Not a circle.

A crescent.

The Sarsen arrangement — particularly the inner trilithon horseshoe — reinforces this, forming a crescent within a crescent.

This is deliberate.

And its orientation matters.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

Death, Not the Sun

Across ancient cultures:

  • The sun represents life and continuity
  • The circle reflects that — endless and complete

But death is different.

Death is transition.

And that transition is often symbolised by the crescent moon — a passage between darkness and renewal.

Stonehenge aligns with this symbolism precisely.

The structure faces the Winter Solstice sunset:

  • The lowest point of the sun
  • The moment of greatest darkness
  • The turning point before light returns

This is not a monument to life.

It is a monument to transition.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Missing Stones Tell the Story

The pattern of missing stones strengthens this interpretation.

If stones had been removed later, we would expect:

  • Random distribution
  • Removal from accessible locations

But instead:

  • The majority of missing stones occur in the south-western quadrant
  • This is the least accessible area

This is not random.

It is intentional.

The monument was designed to be open in this direction — forming a crescent aligned with the Winter Solstice sunset.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Altar Stone and the Slaughter Stone

At the centre of the monument lies the Altar Stone:

  • Fine-grained sandstone
  • Rich in mica
  • Distinct from all other stones

It is also placed flat.

This is unusual — but not unique.

Near the entrance lies the Slaughter Stone, also recumbent.

Excavations in the 1920s showed:

  • The chalk beneath it was deliberately levelled
  • It was always intended to lie flat

Even more importantly:

  • It sits in a shallow depression
  • Connected to the ditch system
  • Likely water-filled under higher groundwater conditions

This would have made the stone appear as a small island in water.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Monument Built in Water

This aligns directly with the hydrological model of early Holocene Britain.

Evidence shows that:

  • Water tables were significantly higher
  • River systems were larger
  • Floodplains dominated the landscape

Stonehenge was not a dry site.

It existed within a water-controlled environment

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Altar Stone: A Geological Clue

The Altar Stone introduces another layer of evidence.

It is widely accepted that:

  • It originates from outside the local region
  • It travelled over long distances

Traditional explanations suggest land transport.

But there is a problem.

Across hundreds of kilometres:

  • No prehistoric roads
  • No engineered trackways
  • No infrastructure for overland movement

What we do find is:

  • Extensive river systems
  • Floodplains
  • Palaeochannels

The conclusion is straightforward:

The stones were transported by water.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Doggerland Origin Hypothesis

There is an additional, often overlooked possibility.

The geological composition of the Altar Stone matches:

  • Bedrock found in northern Britain
  • And bedrock mapped beneath the North Sea

This is critical.

Because during the early Holocene:

  • The North Sea was not fully submerged
  • It was a vast landmass

Doggerland.

If the Altar Stone originated from this region, then:

  • It was not just transported across distance
  • It was brought from a landscape that no longer exists
(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Lost Source Beneath the Sea

Geological evidence shows that Doggerland:

  • Contained exposed bedrock
  • Shared lithological characteristics with the Altar Stone
  • Was progressively flooded between ~9000 and 8000 years ago

This reframes the stone completely.

It is no longer just imported material.

It becomes:

a fragment of a lost homeland.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Deliberate Sightline

The Altar Stone and Slaughter Stone form a direct alignment:

  • From the centre
  • Through the entrance
  • Along the Avenue
  • Toward the ancient river system

When extended beyond the monument, this line points toward:

Doggerland.

This is not coincidence.

Ancient monuments frequently connect:

  • Structure
  • Landscape
  • Memory

Stonehenge does all three.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Monument Built from Memory

When combined:

  • Crescent design
  • Solstice alignment
  • Directional sightline
  • Geological connection

The interpretation becomes clear.

Stonehenge is not simply pointing toward a lost world.

It may contain material from it.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Hidden Interior: Stonehenge as a Painted Space

There is another overlooked feature.

The inner faces of the Sarsen stones are flattened.

This required:

  • Significant labour
  • Controlled shaping
  • Time investment across multiple stones

This was not done casually.

It was done for a reason.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Effort Behind the Surfaces

Flattening stone with prehistoric tools would have taken:

  • Weeks per stone
  • Possibly months across the structure

Prehistoric societies do not waste effort.

Every action has purpose.

These surfaces were prepared for something important.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Cultural Memory Lost

Before the Ice Age, the ancestors of these builders created:

  • Complex cave art
  • Symbolic imagery
  • Advanced visual culture

After this period, the art seems to disappear.

But it didn’t.

The medium changed

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

The Missing Medium

We know:

  • Pigments were used
  • Bodies were painted
  • Symbolism was central

But open-air artwork does not survive:

  • Rain erodes it
  • Sunlight fades it
  • Time destroys it

Over 10,000 years, it vanishes.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

Stonehenge as an Art Space

Now reconsider the monument:

  • Flattened inner stone surfaces
  • Enclosed space
  • Controlled environment

These are perfect conditions for:

painting

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Prehistoric Gallery

Instead of bare stone, imagine:

  • Painted surfaces
  • Symbolic imagery
  • Cultural storytelling
  • Ancestral representation

Stonehenge becomes:

a sacred visual environment


From Cold Stone to Living Culture

What we see today:

  • Weathered stone
  • Empty surfaces
  • Structural remains

What once existed:

  • Colour
  • Meaning
  • Cultural expression

Not a ruin.

But a gallery of memory and identity.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

A Memorial to a Lost World

When all evidence is combined:

  • The crescent form reflects death
  • The solstice alignment marks transition
  • The sightline points toward Doggerland
  • The Altar Stone may originate from that drowned land
  • The interior may have been painted with cultural memory

The meaning becomes clear.

Stonehenge is not a solar temple.

It is a memorial.

(The Stonehenge Crescent: A Monument to a Lost World)
(The Stonehenge Crescent: A Monument to a Lost World)

Final Conclusion

Stonehenge was not built to mark the movement of the sun.

It was built to remember.

To record a moment in human history when:

  • A landscape was lost
  • A homeland disappeared
  • A civilisation adapted

The stones do not just stand.

They point.

They align.

They remember.

And once you remove the myth of the circle, the monument finally makes sense.

Stonehenge was never a circle.
It was a message.

Britain’s First Road – Stonehenge Avenue

Introduction

Traditional archaeology has long struggled to explain the function of the Stonehenge Avenue. As a result, it has been variously described as ceremonial, symbolic, or a natural feature later adopted by monument builders. None of these explanations withstands close scrutiny once the physical evidence is examined in full.

The Avenue is not symbolic.
It is not accidental.
And it is not ceremonial by default.

It is an engineered roadway.


The Failure of the “Preglacial Stripe” Hypothesis

Traditional archaeologists argue that the Avenue pre-dates Stonehenge as a natural feature. Excavations revealed what were described as “preglacial stripes”, interpreted as frost-thaw features formed during tundra conditions at the end of the last Ice Age. According to this view, Stonehenge was placed here because of these stripes.

This explanation collapses immediately under spatial logic.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

The so-called stripes appear only within a narrow corridor approximately twenty feet wide, following the exact line of the Avenue. They do not occur across the surrounding landscape, despite identical geology. The chalk bedrock in this area is uniform and widespread. If these stripes were natural periglacial features, they would appear everywhere — not confined to a single linear path.

Their confinement to the Avenue is decisive.
They are not geological.
They are anthropogenic.


LiDAR Evidence: A Road with Edged Ditches

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

LiDAR removes vegetation and modern disturbance, revealing the Avenue with clarity. What appears is unmistakable:

• a raised linear surface
• flanked by parallel ditches
• consistent width
• controlled gradient

This is not erosion.
This is not chance.

It is a constructed roadway with drainage.

Changing colour palettes on the LiDAR further enhances internal detail, showing wear patterns within the Avenue itself. Excavation confirms what the remote sensing suggests.


Cart Tracks: The Critical Empirical Evidence

Within the Avenue, excavations have revealed wheel ruts — the most overlooked and most important evidence associated with the site.

Some of these ruts are shallow and relatively light. These are consistent with later historic traffic: carts and carriages weighing approximately 1,500 to 1,800 pounds, around 0.8 tonnes. These tracks align with use recorded in historic drawings, including those made by William Stukeley in the eighteenth century.

But beneath them are far deeper cuts.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

These cannot be produced by light vehicles. They require extreme axle loads and slow movement — exactly what would be expected from heavy wheeled transport used to move 25-tonne sarsen stones during the Neolithic.

These deep ruts were misidentified as natural stripes only because their true mechanical origin was never considered.

They are not frost scars.
They are load scars.

Once recognised as such, the Avenue’s function becomes unavoidable.


The Avenue Does Not “Wander” to the River

Conventional interpretations claim that the Avenue takes a long, ceremonial walk down to the present course of the River Avon, passing the so-called King Barrows on the opposite ridge.

This idea is based on modern footpaths and later OS mapping, not archaeology.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

Early Ordnance Survey maps do not show this route.
Nor does the physical ground support it.

At the end of the Avenue, the valley floor opens and appears to split — exactly as shown in Stukeley’s eighteenth-century drawings. However, the shallow later tracks here are insignificant when compared to the deeply engineered cut of the original Avenue.

The Avenue originally terminated at the Neolithic shoreline, not the modern river course.


Transport Phases: Bluestones First, Sarsens Last

The Avenue was used over thousands of years, adapting to a retreating shoreline.

In its earliest phase, during the Late Mesolithic and Early Neolithic, it functioned as a water-edge access route, bringing bluestones inland from the west. The angled post holes along the Avenue cannot serve any practical purpose other than mooring posts, aligned deliberately to changing shorelines — a pattern also seen in the former Stonehenge car park excavations.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

Later, as water levels dropped, the Avenue was extended and reinforced to support heavy overland transport, culminating in the movement of the sarsen stones from the valley floor up to the monument.

The deepest cart ruts belong to this final phase.


The Avenue Mounds: Unloading Platforms

Within the Avenue are two artificial flint mounds.

One is known as Newall’s Mount.
The other remains unnamed.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

These mounds have no defensive, ceremonial, or symbolic explanation. They are too low, too functional, and too precisely located.

Their purpose is obvious: raised unloading platforms for boats operating on the Neolithic River Avon. Identical features exist at Avebury and Silbury, forming a repeated architectural solution to the same logistical problem.


Ditches, Water, and Engineering Logic

The Avenue incorporates deliberate water management.

The southern ditch is shallower because the river lies on that side and water access is immediate.
The northern ditch is approximately 10% deeper, compensating for distance from the water source.

Britain's First Road - Stonehenge Avenue
Britain’s First Road – Stonehenge Avenue

This exact asymmetry is repeated at Stonehenge itself, where the north-western sector of the main ditch is also deeper.

This is not ritual.
It is hydraulic calibration.


Conclusion: Britain’s First Engineered Road

The Stonehenge Avenue is not ceremonial by default.
It is not natural.
And it is not symbolic guesswork.

It is Britain’s earliest engineered road — designed first for boats, then for carts, and finally for the heaviest loads ever moved in prehistoric Britain.

The cart tracks prove it.
The LiDAR confirms it.
The hydrology explains it.

Everything else is narrative, built to avoid confronting what the ground itself is saying.

2026 – Update Freshwater Shells, Alluvium, and the End of the “Dry Stonehenge” Myth

In our previous article, Stonehenge Was Flooded: What the Boreholes Actually Show, we demonstrated that subsurface data beneath and immediately around Stonehenge is incompatible with a dry chalk environment throughout the Holocene.


That article focused on borehole stratigraphy: gravels, sands, voids, reworked flint, and repeated water-sorted horizons occurring well below topsoil.

This follow-up adds what can only be described as a smoking gun.

Freshwater shells.

Not found in trenches.
Not found in ritual contexts.
Not explained away as surface contamination.

But found sealed within borehole sequences, at elevations that only make sense if Stonehenge was once hydraulically connected to a river system.

Freshwater shells do not lie

The graphic above plots three boreholes against terrace height and modern groundwater level. What immediately stands out is not just the presence of freshwater shells, but where they occur:

  • at multiple depths
  • across more than one borehole
  • within water-sorted deposits
  • well below any plausible archaeological horizon

Shells behave differently from flint.

Flint can be dismissed as “residual”.
Shells cannot.

Freshwater shells do not form in dry chalk, they are not produced by springs, and they are not carried downslope by soil creep. Their only viable mode of emplacement is transport and deposition by flowing water within an active fluvial system.

That is basic hydrology.

Why this matters more than any single borehole

On their own, boreholes showing gravels or sands are often waved away as local anomalies. Archaeology has done this for decades.

But once freshwater shells are present, that escape route closes.

Shells require:

  • sustained aquatic habitat upstream
  • lateral transport
  • deposition within a water-moving system

In other words:

If freshwater shells exist beneath Stonehenge, Stonehenge was not hydrologically isolated.

It must have been connected — directly or seasonally — to the River Avon system.

There is no third option.

The missing piece: alluvium finally acknowledged

This is where the newly cited report becomes critical.

For decades, the claim that “Stonehenge bottom was dry in the Holocene” rested on one assumption:
that no fluvial deposits existed in the surrounding landscape.

That assumption is now demonstrably false.

The Winterbourne Stoke East Archaeological Evaluation Report explicitly identifies:

  • alluvium in the valley bottom
  • floodplain deposits
  • Holocene sediment movement by water
  • buried soils and palaeochannel features

You can read the report directly here:
👉 https://wessexarchaeologylibrary.org/library/repository/object/160/download/179/

This matters because alluvium has a precise meaning. It is not “wet ground”. It is not slopewash. It is not groundwater seepage.

Alluvium is river-deposited sediment.

So we now have, independently:

  • alluvium proving river activity in the landscape
  • boreholes proving water-sorted material beneath Stonehenge
  • freshwater shells prove aquatic transport and deposition

That combination is devastating to the dry-chalk model.

Why periodic flooding without a river does not work

A common fallback argument is “periodic flooding”.

But flooding from what?

Springs do not create alluvium.


Rainfall does not sort shells into subsurface layers.
Groundwater rise does not transport sediment laterally.

Flooding only exists because a river overtops its banks.

Once alluvium is acknowledged — as this report now does — a river is no longer optional. It is required.

What this means for Stonehenge itself

Taken together, the evidence now shows:

  • Stonehenge sits at a terrace height consistent with fluvial influence
  • The monument bottom lies within a former wet basin
  • Subsurface deposits show repeated water movement
  • Freshwater shells confirm aquatic transport
  • The surrounding landscape contains floodplain alluvium

The conclusion is no longer radical, it is simply logical:

Stonehenge was once surrounded by water, and functioned within a river-connected landscape.

That has direct consequences for how the stones arrived.

The Avenue re-interpreted

If Stonehenge was hydraulically connected to the Avon system, then The Avenue stops being a ceremonial path and becomes something far more practical:

A managed water-linked route between river and monument.

Moving multi-ton stones by water is trivial compared to dragging them across dry chalk.


Every ancient riverine culture understood this.
Britain was no exception.

Where this now leaves the evidence

We are no longer talking about one or two anomalies.

Across more than 200 logged samples from Stonehenge bottom, we now have:

  • gravels
  • sands
  • voids
  • reworked flint
  • freshwater shells
  • floodplain alluvium
  • palaeochannel indicators

All pointing the same way.

Not ritual.
Not symbolism.
Hydrology.

Final point (and this matters)

The idea that Stonehenge stood isolated on dry chalk throughout the Holocene was never proven.


It was assumed.

That assumption no longer survives contact with the data.

Freshwater shells are the smoking gun — and the alluvium has finally been acknowledged.

The landscape was wet.
The monument was connected.

And water, not land, explains how Stonehenge worked — and how it was built.

The Prehistoric AI Team 🤖

NB: The first graphic shows two boreholes placed at the margins of the Stonehenge basin, where freshwater shells would be expected if the monument once lay on a river shoreline. Shells occur at these edges and are absent from the centre until around 66.60 m OD, where the former channel reaches the basin floor. This is the same infilling pattern seen at Avebury, where a once-open river course has been choked by sediment from surrounding higher ground over the last ~5,000 years. With the present groundwater table at 75 m OD, the system remains hydraulically live; remove the infill and the river would flow again. The evidence is now unequivocal. The second is from the official A303 Tunnel report showing how shallow is the water table to the bottom of the ditch.

In-depth at certain points. The presence of this trench suggests a purpose beyond the ceremonial, indicating either practical or symbolic significance. While there is no direct evidence of a connection between the ditch and the existing moat, it becomes unnecessary given the porous nature of chalk, which allows water to flow over short distances.

Stonehenge as a Hydrological Case Study

Stonehenge occupies a low-lying basin within a chalk landscape that functions as a regionally connected aquifer rather than a dry, impermeable surface. Chalk terrains absorb rainfall, transmit groundwater laterally over wide areas, and express excess water through rivers and wetlands at topographic lows. In post-glacial conditions—characterised by high recharge, limited vegetation, and reduced evapotranspiration—groundwater tables would have been substantially higher than today. Under such conditions, river systems expand laterally, valley floors remain saturated, and shallow basins become hydraulically active components of the wider fluvial network (British Geological Survey, British Upper Cretaceous Stratigraphy; Wessex Archaeology, Winterbourne Stoke East Archaeological Evaluation Report). From a physical standpoint, hydrological connectivity is therefore the expected condition, not an exception.

At Stonehenge, this expectation is reinforced by independent subsurface and engineering evidence. Borehole records around the monument document water-sorted sediments and freshwater shells at depth, while landscape investigations identify alluvium and floodplain deposits within adjacent valleys (Wessex Archaeology, Winterbourne Stoke East Archaeological Evaluation Report). Crucially, tunnel ground-investigation cross-sections prepared for the A303 scheme show Stonehenge Bottom as a structurally controlled groundwater basin, with measured groundwater levels intersecting the basin floor and permeability contrasts forcing hydraulic convergence (Highways England, Implications of 2018 Ground Investigations to the Groundwater Risk Assessment, REP3-019; reproduced in Stonehenge Alliance, Written Summaries of Oral Submissions at ISH10). These data demonstrate that Stonehenge was not hydrologically isolated but formed part of a river-connected landscape linked to the River Avon system. When viewed in this context, the Avenue resolves as a water-aligned route rather than a purely ceremonial path, and stone transport by water becomes a practical consequence of post-glacial chalk hydrology rather than a speculative alternative.

Author’s Biography

Robert John Langdon, a polymathic luminary, emerges as a writer, historian, and eminent specialist in LiDAR Landscape Archaeology.

His intellectual voyage has interwoven with stints as an astute scrutineer for governmental realms and grand corporate bastions, a tapestry spanning British Telecommunications, Cable and Wireless, British Gas, and the esteemed University of London.

A decade hence, Robert’s transition into retirement unfurled a chapter of insatiable curiosity. This phase saw him immerse himself in Politics, Archaeology, Philosophy, and the enigmatic realm of Quantum Mechanics. His academic odyssey traversed the venerable corridors of knowledge hubs such as the Museum of London, University College London, Birkbeck College, The City Literature Institute, and Chichester University.

In the symphony of his life, Robert is a custodian of three progeny and a pair of cherished grandchildren. His sanctuary lies ensconced in the embrace of West Wales, where he inhabits an isolated cottage, its windows framing a vista of the boundless sea – a retreat from the scrutinous gaze of the Her Majesty’s Revenue and Customs, an amiable clandestinity in the lap of nature’s embrace.

Exploring Prehistoric Britain: A Journey Through Time

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives based on cutting-edge research, particularly using LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualizes my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp, also receive a re-evaluation based on LiDAR analysis in my posts Lidar Investigation Cissbury Ring through time and Lidar Investigation White Sheet Camp, revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to the topic of ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts including Car Dyke – ABC News PodCast and Lidar Investigation Car Dyke – North Section, suggesting a Mesolithic origin2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis which has helped to inform the landscape transformations over time. I have discussed this hypothesis in several posts including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes the astronomical insights of ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.

Stonehenge Solved – Pythagorean maths put to use 4,000 years before he was born

Introduction

Suppose we examine the skills of what traditional archaeologists call the ‘Megalithic People’ – the civilisation that created the first stone monuments. We notice that to achieve such grand constructions, they would have required advanced mathematics, which to date has been credited to the ancient Greeks. By undertaking a closer, detailed analysis of monuments such as Stonehenge and, more importantly, the mathematics used to design them, we can see that these constructions, which are approximately ten thousand years old, were based on sound and accurate trigonometrical theory.(Stonehenge Solved)

How was Stonehenge planned, and what can we infer from the ‘blueprint’ about the knowledge of mathematics that they possessed?

The Stonehenge Blueprint

Firstly, Stonehenge was built in two distinct phases. Current archaeologists are confused by the monument and the dating of the structure; therefore, if you read or browse the internet, you will see the ‘traditionalist’ quote referring to three to five phases. Moreover, these phases occurred AFTER the original monument was abandoned, and thousands of years later, the ritualistic Celts occupied the memorial and used it to worship the Sun and the Summer Solstice, as we see re-enacted today during the summer solstice.

The First Phase took place around 8300 BCE, when our ancestors built the original ditch, composed of individual pits cut below the ancient groundwater table level to create a moat.   This moat was used with the Bluestones to bathe away infections from cuts and bites, which would have turned into gangrene and lethal fevers if left untreated.  Bluestones (when wet) release chemicals, including the most potent natural antiseptic – rock salt..(Stonehenge Solved)

 (Stonehenge solved)
Stonehenge Phase I -Stonehenge solved

The most remarkable aspect is the accuracy of the diameter of this moat, which is precisely 360 ft (109.73m). This length is no accident or coincidence; it is the reason that our angular and trigonometrical system revolves around 360!

We have 12 months a year, and each has a lunar cycle that lasts (from New Moon to New Moon) 29.53 days.   There were 56 Bluestones (2 x 28), and we can demonstrate that this was used as a highly accurate (99.8%) moon and eclipse calendar, which could compensate for the 0.47-day discrepancy between the moon cycle and a 30-day standard cycle.  It is, therefore, no surprise that the most ancient of calendars are 12 x 30 = 360 days in length.

In history, we know that in the eighth century BCE, civilisations worldwide either discarded or modified their old 360-day calendars. The 360-day calendars had been in use for the majority of the past millennium.  In many places, month lengths immediately after that change were not fixed but were based instead upon observing the sky.

Priest-astronomers were assigned the duty of declaring when a new month began – it was usually said to have started at the first sighting of a new moon. The length of a month at that time was simply the number of days that passed from one new lunar crescent to the next.

For example, during those years in Rome, a Pontifex (priest) observed the sky and announced a new moon and, therefore, the new month to the king. For centuries afterwards, Romans referred to the first day of each new month as Kalends, derived from their word calare (meaning “to announce solemnly” or “to call out”).  The word calendar is derived from this custom.

The ancient Babylonians, around 4000 BCE, used a calendar with alternating 29-day and 30-day months. This system required the addition of an extra month three times every eight years. As a further adjustment, the king would periodically order the insertion of an additional month into the calendar. However, it is interesting that the monument becomes a ‘time capsule’ from our ancestors, showing us that they understood the mysteries of mathematics.  When a circle, a diameter of 360 ft has a moated circumference (the area around the edge of the circle) of 1130 ft in length.  So if we divide the measurement around the edge 1130 by the diameter 360, we get a fascinating number 3.14 – why is this absorbing, because it’s what we know as PI or 3.14159!! .(Stonehenge Solved)

 (Stonehenge solved)
Greek Symbol for PI – Stonehenge solved

Did the builders of Stonehenge leave us a message in stone?

 (Stonehenge solved)
Trilithon used as a symbol for PI – Stonehenge solved

No one knows who invented Pi, yet the Ancient Greeks used this unusual symbol to denote pi – does it remind you of some monument we have been discussing? Why would the Greeks use such a symbol to represent the relationship of a circle to its diameter? Indeed, you would use something round, not a classic trilithon symbol as found at Stonehenge – unless, of course, that’s where it was first used!

Now, 360 is also an exciting number when it comes to circles, as there are 360 degrees in a circle.  This is a particular number, for if you were to pick a standard number to determine the degrees in a circle, would you not opt for something more manageable and obvious to remember and use, like 360?

Such a number is not suitable for trigonometry, as a standard right-angle triangle with a 360-degree circle has 90-60-30, which allows for simple mental math calculations, such as determining the sides of a triangle. For if it were based on a 100-degree circle, the triangle angles would be 25 – 16.66 – 8.33, and the ability to calculate angles in your head or as an approximation (no electronic calculators in the Stone Age) would be far more complex.

The logic behind linking the degrees (or days) in a circle or solar year is evident and is reflected in humanity’s earliest stone constructions, such as Stonehenge.  However, Pi is only the start of this amazing construction, and the work attributed to Pythagoras in the past must now be questioned..(Stonehenge Solved)

Phase II construction

Four thousand years after the original Phase I Circle was constructed with the 58 Aubrey Holes that held Bluestones from the Preseli Mountains in Wales. These stones were used for mapping the 360-day lunar calendar; they decided to erect an additional central monument.

In the second book of the Prehistoric Trilogy: ‘The Stonehenge Enigma’ – I proved that this monument was a temple to the dead of Doggerland, who died in an earthquake and subsequent tsunami in about 4200 BCE, as recorded within Plato’s dialogues. Like a relief map of Doggerland (Slaughter Stone) and the Altar Stone (both are the only two deliberate recumbent stones), which directly point to the ancient island and were included at the time of construction..(Stonehenge Solved)

 (Stonehenge solved)
WE ARE HERE!! – Mankind has always left obscure ‘time capsules’ to future (or alien) generations – Stonehenge solved

Phase II of this construction included a new entrance causeway surrounded by moats known today as ‘The Avenue’, which led to the Neolithic shoreline in the dry river valley at Stonehenge Bottom.  This 600 m ‘road’ was used not only to transport people to the monument, but also to move the larger Sarsen stones (weighing up to 16 tonnes) by boat from the Marlborough Downs near Avebury to the new monument at Stonehenge, a distance of between 20 and 25 miles.

However, rather than just building any road to the shoreline, they decided to make it along an alignment that marks the longest day of the year—the Summer Solstice.  This day was significant for our ancestors as it corrected the 360-day lunar calendar to align with the solar calendar, which is five days longer (365 days, which we use today).  In the centre of The Avenue, they placed two stones (which are now missing) that are in exact alignment with the sunrise when this monument was first constructed.

This alignment provides us with the ‘best’ date for the construction of Stonehenge (as carbon dating is not possible for the stones or the stone holes) and confirms the date of Doggerland’s demise at 4200 BCE.

What we have now is our first ‘chord’ alignment, which corresponds to the diameter of the Stonehenge ditch and the starting point of the circle, aligning with The Avenue..(Stonehenge Solved)

 (Stonehenge solved)
Stonehenge Phase II plan reconstruction – Stonehenge solved

From this start, they then sub-divided the circle up into six portions called a ‘Hexagram’ in mathematical terms for as we will show you in the book ‘Dawn of the Lost  Civilisation’, the number six and its multiples are significant to our ancestors.

 (Stonehenge solved)
Properties of a pythagorean equilateral triangle – Stonehenge solved

The Hexagram was constructed by a series of strings of the same length (centre of the monument to the ditch), creating six ‘equilateral’ triangles, with all three sides the same length, and therefore all three angles are of 60 degrees.

Stonehenge Stage II – Hexagram reconstruction – Stonehenge solved

A crescent of stones was then formed for the monument for the temple was dedicated to the dead and, therefore, would have represented the crescent moon, NOT  the Sun as some currently believe, for this adaptation occurred when later Druids altered the site by adding smaller stones and re-positioning the outer circle of bluestones.

 (Stonehenge solved)
Stonehenge Stage II – Outer Circle Added reconstruction – Stonehenge solved

Then the five pairs of the trilithon stones in the inner horseshoe were added, making sure the gaps between the stones followed the alignment corresponded to the hexagram design. Lastly, the smaller outer circle trilithon which was aligned with the winter solstice sunset, was added to complete the monument.

 (Stonehenge solved)
Stonehenge Stage II – Trilithons added reconstruction – Stonehenge solved

Belief System

The Hexagram is a mandala symbol called satkona yantra or sadkona yantra found on ancient South Indian Hindu temples. It symbolises the nara-narayana, or perfect meditative state of balance achieved between Man and God, and if maintained, results in “moksha,” or “nirvana” (release from the bounds of the earthly world and its material trappings).

Is this what we see in the construction of Stonehenge – humanity’s first religious beliefs of ‘Man’ the bottom triangle pointing up and God or Spirit world the triangle pointing or looking down? .(Stonehenge Solved)

 (Stonehenge solved)
Stonehenge plan reconstruction – Stonehenge solved

We know about Stonehenge that it was a temple to the dead of Doggerland constructed at the same time that Doggerland was swamped by the rising sea levels we are still experiencing today.  This disappearing peninsula started to erode some ten thousand years ago, directly after the last Ice Age had ended and the seas began to rise, which over the course of the next six thousand years left this once mighty land as a small island Plato called Atlantis..(Stonehenge Solved)

How the Original Stonehenge would have looked a ‘Crescent Moon’ – Stonehenge solved

So, why is a foot 12 inches and what is the unit of measurement to do with the builders of Stonehenge?

Another ‘Thing that doesn’t make sense in History’ is the ‘Foot’.  We call it an ‘imperial unit measurement.’ But where does it come from?

Wikipedia will tell you:

Historically the foot, which was used in Ancient Greece, Ancient Rome, England, Scotland and many Continental European countries and which varied from country to country and in some cases from city to city, was part local systems of units. Its length was usually between 250 mm and 335 mm and was generally, but not always, subdivided into 12 inches or 16 digits.

We know it’s old, but we have no idea who invented it or why they divided the unit into 12 or 16 inches or digits.  As we have already stated, the Stonehenge moat is 360 feet wide, and we have demonstrated that it was constructed using a system of simple strings in a hexagonal pattern.

So, how would the first civilisation measure distance?

The most natural way to measure distance is with your own body.   How many times do we measure another imperial unit of measurement called a yard quickly, without a ruler or other measuring device? – We take a big step. In sports, we see linemen and referees mark out, say, a 10-yard penalty by taking ten long strides or measuring from the tips of their fingers to the middle of their chest, which is approximately 3 feet (depending on the height of the individual).   So, it’s not quite rocket science to understand that physical attributes were the first units of measurement, so let’s go back to the foot. Can we make a good guess where the measurement foot comes from and what physical form it refers to?

 (Stonehenge solved)
Measurement is historically a proportion of the architects body size – Stonehenge solved

But there is a problem. Who has a foot that is 12inches long, and what is an inch?

An inch of a digit is the width of ‘your digit’ or thumb to be accurate. Therefore, the builders of Stonehenge would and did use two different physical aspects to confirm their measurement, either one foot in front of another or a long stride. The problem for archaeologists and anthropologists is that the Greeks and Romans were only about five to five and a half feet tall, and their feet at best were only 9 inches long, so they cannot be the source of this oldest measurement scale.

The person with a 12-inch foot needs to have a size 15 shoe, and because your shoe size is proportionate to your height, that is an individual over 6 foot 6 inches tall.  So, does this give us an indication of whom these people were? Can we now identify the ‘megalithic people’ that constructed the stone monuments of Europe?.(Stonehenge Solved)

 (Stonehenge solved)
Cro-magnons had six fingers and hence 12 digits to a foot (also with 6 toes) – Stonehenge solved

There has only been one identified group of Homo sapiens with this physical attribute in anthropological history – Cro-Magnon man.

Fifty thousand years ago, Homo sapiens emerged from Africa after approximately one million years of evolution. These hunter-gatherers were forced out of their rich tropical rainforests (which we now call the Sahara Desert) as climate change devoured their habitat. So, through necessity and survival, they followed the herds into the Middle East and found a gigantic lake called the Caspian Sea, where they came face-to-face with a species they had never seen before in humanity.

Man’s evolutionary cousins, Homo Neanderthals, had been living in this place even longer than Sapiens existed, for they too had walked ‘out of Africa’ a million years earlier and spread themselves across the known world into small, isolated tribes.   However, Neanderthals were very different from their later relatives, as they were bigger, stronger, and more intelligent than the sleeker, faster, and more agile Sapiens. .(Stonehenge Solved)

But then something extraordinary happened!

Cro-Magnons

Something that would change the world for the rest of eternity, for the chance meeting of these two species would revolutionise the evolution process as ‘Stone-Age man’ would become ‘Rocket man’ in just thirty thousand years – a mere twinkle of a Darwinian eye in comparison to the millions of years that humanity had existed. And it all started with the firstborn of a cross-breed between these two species – for this was the first Cro-Magnon.

The Cro-Magnons are over six feet tall; they are upright, fast, and agile, but moreover, they are vastly intelligent and able to adapt quickly and effectively.  They have a massive brain capacity and are capable of abstract thought – in reality, they are Homo Superior on the evolutionary scale.

In the Caspian Sea, they and their blonde/red-haired, blue/green-eyed civilisation-built boats from reed banks and sail the inland rivers to a place called Europe. The last ice age slowed their progress as it took effect on the land and wiped out their Neanderthal cousins, who could not adapt as their offspring; however, finally sheltered within the caves of the Dordogne in France, where humanity for the first time learned to paint, play music and weave cloth, while they waited for the long winter to subside.

They then followed the herds north in their boats to a new world created by this ice age, which had vast, fertile land rich in fruits and animals.   This is where they finally settled, hunted, traded and communicated to grow a new civilisation of ancient mythology we know today..(Stonehenge Solved)

 (Stonehenge solved)
Homo Sapiens and Neanderthals made Cro-Magnons – Stonehenge solved

This society used stone to build the world’s first monuments, such as Stonehenge, Newgrange, and Carnac.  They were the ‘Megalithic Builders’ of prehistory, but they also built much greater constructions than temples and stone circles; they ultimately created the most fantastic ancient city known to humankind – Atlantis.

Underneath the North Sea lies the lost city of Atlantis, flooded by the rising tides of the Ice Age as described by Plato.    This civilisation travels the whole world in ships of reed to ‘seed’ colonies throughout the earth, including the Mediterranean, Americas, and as far as India, until one day a massive tidal wave wipes out this once great civilisation, leaving just isolated remnants throughout the world,  which integrated with the local Homo sapiens to create the society we know today.

Part of this lost civilisation migrated to the Mediterranean, as Plato’s writings suggest, and not only ‘seeded’ their ancient culture, but also gave them knowledge of construction and mathematics, which is the basis of most of Pythagoras’ work.   The Greeks did not reinvent the units of measurement, such as the foot or inch; they incorporated them into their society, which is why confusion persists among current historians and archaeologists who are unaware of the units’ origins.

However, this is not science fiction – this story is true and can now be proven by science. The “Truth is stranger than fiction,” as Mark Twain once said.

Author’s Biography

Robert John Langdon, a polymathic luminary, emerges as a writer, historian, and eminent specialist in LiDAR Landscape Archaeology.

His intellectual voyage has interwoven with stints as an astute scrutineer for governmental realms and grand corporate bastions, a tapestry spanning British Telecommunications, Cable and Wireless, British Gas, and the esteemed University of London.

A decade hence, Robert’s transition into retirement unfurled a chapter of insatiable curiosity. This phase saw him immerse himself in Politics, Archaeology, Philosophy, and the enigmatic realm of Quantum Mechanics. His academic odyssey traversed the venerable corridors of knowledge hubs such as the Museum of London, University College London, Birkbeck College, The City Literature Institute, and Chichester University.

In the symphony of his life, Robert is a custodian of three progeny and a pair of cherished grandchildren. His sanctuary lies ensconced in the embrace of West Wales, where he inhabits an isolated cottage, its windows framing a vista of the boundless sea – a retreat from the scrutinous gaze of the Her Majesty’s Revenue and Customs, an amiable clandestinity in the lap of nature’s embrace.

Exploring Prehistoric Britain: A Journey Through Time

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives based on cutting-edge research, particularly using LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualizes my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp, also receive a re-evaluation based on LiDAR analysis in my posts Lidar Investigation Cissbury Ring through time and Lidar Investigation White Sheet Camp, revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to the topic of ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts including Car Dyke – ABC News PodCast and Lidar Investigation Car Dyke – North Section, suggesting a Mesolithic origin2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis which has helped to inform the landscape transformations over time. I have discussed this hypothesis in several posts including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes the astronomical insights of ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.

Silbury Avenue – Avebury’s First Stone Avenue

Introduction

In 2014 a third stone‑lined processional way was recognised within the Avebury UNESCO World Heritage landscape. Archaeologists have long known the West Kennet Avenue and the Beckhampton Avenue, because many of their giant sarsen uprights still punctuate the fields. Nobody had imagined a hidden counterpart until a band of subtle turf marks on Waden Hill was spotted in enhanced air‑photos and ground‑truthed on the slope (see Silbury Avenue – Avebury’s First Stone Avenue). I have provisionally christened the new line “Silbury Avenue,” because it climbs the ridge and then would have descended towards Silbury Hill.

Digital enhancement revealed a ribbon of greener “patches” stretching roughly 470 m up Waden Hill’s north‑west flank; if the sockets continued down to the Kennet flood‑plain the avenue would total about 1.47 km. Counting the colour anomalies indicates at least nineteen stone‑pairs, each ≈ 25 m apart and defining a corridor 15–20 m wide — essentially a match for West Kennet Avenue, whose stones stand 22–24 m apart across a path 15–17 m wide (Stonehenge Stone Transportation Hoax).

Back in 1936 Keiller & Piggott excavated the northern arm of West Kennet Avenue and discovered it had been set out as ten ruler‑straight segments, not William Stukeley’s elegant serpent (Keiller & Piggott 1936). Their plan shows the line drifting west of Avebury’s south entrance; later pairs kink back in a pronounced zig‑zag. Explanations have varied: a prehistoric surveying blunder (Burl 2002), a drafting error in Keiller’s plan (Gillings & Pollard 2004), or deliberate symbolic geometry (Sims 2009). Silbury Avenue resolves the puzzle: the earliest stones formed a direct line between Avebury and Silbury Hill; when processional emphasis later shifted south‑east toward The Sanctuary, masons grafted a dog‑leg onto that older axis.

The ‘Zig Zag’ Avenue currently seen is simply explained – Silbury Avenue – Avebury’s First Stone Avenue

A New Three‑Dimensional Landscape

Silbury Avenue does not take the beeline to Silbury Hill; instead it climbs the ridge crest. There, nine Bronze‑Age round barrows flank — yet never interrupt — the stone‑line, proving the avenue is older than the mounds. A 1913 water‑pipe trench near the crest cut an oval pit filled with Windmill Hill sherds, burnt flint and animal bone, hinting at Mesolithic–Neolithic activity long before the barrows rose (Whitehead & Edmunds 2012).

The ridge offered practical advantages: carts or sledges avoided the steepest gradient and travellers gained a sweeping view of the Kennet valley. That stance is exactly where Silbury Hill’s beacon would first appear to a procession leaving Avebury, tying topography to spectacle.

Where Silbury Avenue Ends 

After cresting Waden Hill the socket‑line does not run straight to Silbury Hill. Instead it veers down the gentle south‑west slope and stops on the flood‑plain at a low, circular mound long nick‑named “Silbaby” (a.k.a. Waden Mound). Early engravings reproduced by Stukeley mark the same bump beside the mediaeval track, and modern LiDAR shows a raised berm about 20 m west of today’s farm lane — almost certainly the original causeway that carried the avenue to the mound (Silbury Avenue – Avebury’s First Stone Avenue).

Silbury Avenue - Avebury's First Stone Avenue
Modern LiDAR shows a raised berm – Silbury Avenue – Avebury’s First Stone Avenue

Local researcher Pete Glastonbury re‑identified the earthwork in 2011, traced the avenue’s last sockets to it, and commissioned coring. Those cores revealed a chalk‑rich matrix and Neolithic–Early‑Bronze‑Age charcoal, contradicting a later suggestion that the mound was post‑mediaeval spoil (Glastonbury pers. comm.; Mesolithic River Avon Case Study). Because Silbaby sits on an artificial spur that channels Waden Spring into the Kennet, it would have projected into open water for much of the year, giving boats deep enough draught to lie alongside even in flood. LiDAR also shows a hard‑packed apron on the south edge. Taken together, the evidence indicates that Silbaby was intentionally constructed as a riverside loading platform—an embanked spot where sledges coming down Silbury Avenue could transfer stones or other cargo onto boats for onward travel along the Kennet.

Reading the avenue this way clarifies two old puzzles. First, the stones climb the ridge because the south‑west descent offers the shallowest haul to the only reliable harbour. Second, the stone‑pairs stop at Silbaby because onward travel switched from road to river: Silbury Hill itself, surrounded by deep winter pools, was never the quay but the lighthouse marking the approach. Silbaby is therefore the functional full‑stop of Silbury Avenue — the hinge where Avebury’s over‑land processions and its riverine trade converged.

Silbaby or Silbury Mount – Silbury Avenue – Avebury’s First Stone Avenue

Implications for Avebury’s Chronology

Recognising Silbaby as the avenue’s terminus shows that West Kennet Avenue’s zig‑zag is not a prehistoric “mistake” but a later splice grafted on when the harbour at Silbury Hill silted up and traffic shifted east to The Sanctuary. John Aubrey’s seventeenth‑century sketch of a matching dog‑leg at the Sanctuary end confirms that both termini are secondary (Stonehenge Stone Transportation Hoax).

Sequence now reads:

  1. Silbury Avenue and Silbaby/Waden Mound laid out first, linking Avebury directly to its beacon‑harbour.
  2. Round barrows added on the ridge, respecting but not intersecting the avenue.
  3. West Kennet Avenue begun as an extension, later kinked south‑east when the Kennet receded and a new unloading ground was needed at The Sanctuary.
  4. Beckhampton Avenue and other monuments accreted as the valley dried further.

Conclusion

Silbury Avenue transforms our mental map of Avebury. What once looked like an eccentric detour now emerges as a freight road engineered for carts, sledges, ceremony — and crucially — for a river harbour that existed only while Kennet levels were higher. Silbaby, the modest mound on the flood‑plain, turns out to be the key: loading platform where land met water, and symbolism merged with logistics.

Future trenching inside Silbaby, coupled with a full socket survey along the south‑west descent, could lock this model in place or overturn it. Either way, recognising the avenue’s true destination forces us to read Avebury’s stones not just as ritual architecture but as part of a dynamic transport system built for a landscape that is now largely lost beneath the plough.
