Robert John Langdon explains his hypothesis - 5 minutes duration

12,000 years ago the last Ice Age finally melted, revealing the Britain we know today... OR DID IT?
Britain had been underneath two miles of ice and the surrounding seas had frozen solid. What was left was a huge icy mass of enormous weight, pushing down on this tiny island. This mass had compressed the earth so much that the land surface lay at least a half a mile below the sea bed as we know it today. 
So what exactly happened after the great ice age melt?
This huge mass of watery ice that covered Britain raised the groundwater tables and left the land totally saturated. In fact, the volume of water was so great that it eventually created the English Channel and the North & Irish Seas. Very slowly, the land then started to rebound, so slowly in fact that even now, parts of Britain are still rising about one cm per year. This melting ice combined with the lowering of the land levels created not the single island called Britain we know today, but a series of smaller islands and waterways - totally unrecognisable to the landscape that is so familiar to us now. 

Britain's Mesolithic landscape

Moreover, the land became a sub-tropical forest as the warmer climate that first melted the polar ice caps encouraged the growth of abundant foliage. This would very probably have caused the islands to experience what we would consider today to be monsoon seasons. Which in turn then kept groundwater tables abnormally high for another 4,000 years? The foliage, groundwater and warm climate would have left the islands resembling more like the Amazonian rain forest, rather than the grassy hills of Britain we see today.
The only way our Mesolithic ancestors of Britain could have had to adjust to this new environment would have been to develop and use their boat and seamanship skills. Consequently, adapting to living and trade by these shorelines travelling via the vast waterways and lakes rather than through the forests, which would have been riddled with dangers such as brown bears, packs of wolfs and wild boar all roaming freely. Therefore, the shorelines became critical – our Mesolithic ancestors would have lived, worked and gathered by these ‘super-waterways’ and would have created social monuments and beacons on there beaches and peninsulas. 
Flooded Britain

My hypothesis proposes that our greatest prehistoric monuments, such as Stonehenge, were built on these watery peninsulas. I also propose that the ditches surrounding henges were NOT dry ditches, as archaeologists currently believe, but were, in fact, constructed to be watery moats and canals, which turned these sites into very special islands. The most astonishing aspect of this hypothesis is that even today, thousands of years after the groundwater have subsided, we can re-visit these sites and identify the ports and channels of this bygone age and by using the landscape, we can date, more accurately than ever before, when the sites were initially constructed.
Another key component of my hypothesis is the discovery of navigational signposts, built within the landscape, on the banks of these waterways. Traditionally, archaeologists have believed that these had religious or ceremonial use, whereas my evidence shows that they had a more functional engineering purpose, helping our ancestors to navigate around these islands. 
In fact, the book will show for the first time, that these signposts guided our ancestors when they transported enormous stones from the Preseli Mountains in Wales to the site at Stonehenge – by boat. These very stones were used to build the first phase this magnificent monument. Even more importantly, I can show the exact location of where these vast stones were unloaded from the boats and how this precious cargo and the mechanism used to lifted onto shore. 
This discovery of this landing site has led us to accurately date for the first time the original construction date of Stonehenge - 7500BC to 8000BC. This is 5,000 years earlier than current archaeological estimations, making Stonehenge probably the oldest Stone Monument in the world.

  1. Firstly I like to say how much I have enjoyed reading The Stonehenge Enigma.As far as a flooded Britain after the ice age goes,I think it makes a compelling argument,especially as,for once, all the ancient structures seem now to have a proper meaning and context.

    I am also supportive of the idea of a pre-ancient civilisation,that may go back tens of thousands of years,perhaps even longer.

    May I just make a couple of comments.Firstly,supposing the theory of isostacy is wrong. Would this seriously affect your hypothesis.The reason I ask this is because,another reseacher has pointed out that it (isostacy) has serious shortcomings.For example:"Antarctica is thought to have supported massive ice sheets for most of the past 15 million years. If the mantle were subject to deformation under such loading, even at a nominal rate of 1 mm/year, the crust there should have subsided by 15 km -- which has obviously not happened. In fact, the Trans-Antarctic mountains, only several million years old, are elevated more than a kilometre above sea level, showing that the lithosphere/mantle is capable of lifting continental ice sheets, rather than being depressed by them"

    My other point relates to Atlantis.The dreaded "A" word is complete anathema to any scientist/researcher embedded in the present world of orthodox Universities and Academic establishments.
    However I always take Atlantis to mean not necessary an actual place (for sake of argument) but a time of both a people and land's now gone,seperated by a long period of catastrophe,perhaps concluding with the end of the last ice age.Given what I have read,I do not believe it came to an end quietly.The era we are speaking of may have been troubled by centuries of tumult,the memories of which have come down to us in stories of upheaval both by fire and flood.
    I think only worldwide disasters could have wiped out the clear imprint of a superior race,that may have existed world wide,not simply in an area in the North Sea.

    There is lots of evidence on the ocean floors of long sunken lands not only in the north sea,but off Ireland, in the Atlantic,off the coast of South America and in both the Indian and Pacific Ocean's.
    Ever since the acceptance of plate tectonics (another theory in crisis) Plato's clear positioning of Atlantis has been questioned and moved around according to the latest evidence or theory.

    If a large population of a superior race had moved to Britain from the North Sea to construct the henges and other ancient sites and structures,what happened to them and their influence ,that they so easily dis-appeared to be replaced by the cruder Ancient Britons that were discovered by the Romans ?

  2. Hi Mark

    I will try to answer each point in turn.

    I illustrate the 'isostacy' movement of the crust as it shows that this weight would have increase the groundwater table levels by compression and that compression would have taken thousands of years to rebound back to a 'normal state' - which is a concept archaeologists and historian have yet to acknowledge or accept. The degree of transformation is questionable as it is a subject only partially explored and I'm sure they will be variations of the years to rate of rebound and compression etc - but the principle will remain the same of rising groundwater tables making flooding of the landscape more probable.

    Atlantis is tainted by fiction and therefore to see the 'wood from the trees' is very difficult. Plato description is a blessing as Plato is a scribe who wrote about conversations of the past and is seen as a founder of philosophy - so in my mind his works must be respected til proved false. The third book of the trilogy - I started writing about six weeks ago goes on to look at myths and legends. I try to extrapolate the true elements from the embellished stories and found to my amazement correlations to the Plato story. All these stories from around the world talk of a single event and of a species that spread around the world creating these myths and stories.

    You quite rightly identify that this was a time of great turmoil and political changes, which interestingly we can still see in our society today as they have never been resolved.

    Think the superior race was not wiped out (but for the sake of survival against greater numbers) was assimilated quietly and secretly into the sapien population. The details of these people and where they can still be found my friend - you will need to wait for the lost book of the trilogy to be published, although I am sure you already have some ideas of your own?


  3. Thank you for your reply Robert.

    On a side note I am very impressed with your responses to all comments (however negative or dismissive) made regarding your Hypothesis.Not only on your own site,but on other websites as well.
    By the way my view is neither negative or dismissive.
    I am still not fully understanding of some of the scientific evidence you present,so I will need to study this a little closer.Which is why I only mentioned the theory of Isostacy,as it seemed to be a central element to your Hypothesis.
    At this point however I will certainly concur with you on a number of points.Atlantis is not a myth,Plato was not simply relating a political allegory,that the last ice age ended during a period of upheavl,which was certainly implicated in the dis-appearance or loss (partial or otherwise) of a great ancient civilization,and that current theories about Stonehenge are bounded up in a rather conventional and staid presumption about what passes for human history.

    I look forward to a continued interest in your Hypothesis and will certainly continue to check out both your publications and your regular posts.

  4. Hi Mark

    I try (not always successful) to keep a balanced view. My business experience in new products development indicated that a 70-30 target for success - no one will get all the evidence right, but if I can get 70% of it correct I will consider the hypothesis workable - so happy to see where I have it wrong.

    There's a story told about a mathematician Dr Jacob Bronowski once knew. Who had colleagues phone him to say they had duplicated his work and found it to be correct - to which the mathematician replied - " please don't bother telling me I'm right, just let me know if I've got something wrong?" It shows a man who knew his limitations as a human being!

    As for post glacial flooding - the evidence has moved on from five years ago. Consequently, the volume of water on the ice cap was so great that the Black and Caspian seas were effected by an increase of the water table. Moreover, this flooding is then a not just a Northern Hemisphere phenomenon, but a world wide one. So although Isostacy was a factor, it is possibly in comparison to the volume of water melting only a small one!


  5. Hello,
    In one of your previous posts, you gave the website address for obtaining the ordnance survey interactive map relating to ice age flooding of UK. Unfortunetaly, I cannot locate it anymore. Could you re-publish the site address? Yours sincerely, CB

    1. Sadly, no INTERACTIVE maps as yet...working on it!! All we have is OS maps based on the first 1800 one inch series for our study area Wiltshire. Although the Southdowns version is completed but yet to be published..time problems sadly!!
