Council for British Archaeology now supports my hypothesis

By Robert John Langdon

In the July/Aug edition of the CBA's magazine British Archaeology an English Heritage's report 'Palaohydrology of the Kennet, swallowhead springs & the Sitting of Silbury Hill' is examined in an article by Steve Marshall about Silbury Hill.

Silbury Hill - surrounded by water

The amazing aspect of this report is that it recognises parts of my hypothesis and accepts that in the Avebury area in prehistoric times, "groundwater levels were 5m higher than today" and the above picture is offered in support of this analysis as it has been customary wet this spring.  They also go on to tell us that " Water in chalk rivers like the Kennet comes mostly from underground, rather than from immediate precipitation.  Modelling ancient groundwater patterns, Whitehead and Edmunds found that the now seasonal Swallowhead spring - dry in summer, wet in winter - would have flown all year round".

Silbury Hill - surrounded by water diagram

This map is a very conservative attempt on mapping the groundwater and ignores the geological facts under the ground which are shown on this map.

Silbury Hill - surrounded by sand

For my regular readers this looks very familiar as all this appeared in this web site and in the First Edition of the Stonehenge Enigma:

Eventually, when Avebury lost all of its groundwater, our ancestors built Silbury Hill as the new landing site to the complex. Silbury Hill is the largest man-made island in Europe, and was set at the end of the Neolithic waterway.  Composed mainly of chalk and clay excavated from the surrounding area, the mound stands 40 metres (130 ft) high and covers about 5 acres. As we have already seen, it would have taken 18 million man hours to deposit and shape this vast pile of chalk and earth on top of the natural hill that forms Silbury’s foundation. The base of the hill is circular, 167 metres (548 ft) in diameter. The summit is flat-topped and 30m (98ft) in diameter.

At this point, to maintain the link to Avebury, the Sanctuary was created and a stone causeway was introduced from the landing site at the end of the peninsula to Avebury.  It should be noted that the original track went North East from the Sanctuary. This path would have taken our ancestors around the groundwater and over the hill to a place called Falkner’s Circle, which has now been destroyed, but once overlooked Avebury.  From this stone circle, the path went down to the existing stone avenue toward Avebury. This stone avenue, like the one at Stonehenge, has a strange kink in its design, as if it went in a different direction before being changed at a later date. The kink shows that the original path led to Falkner’s Circle, and we believe this was the route our ancestors used in the Neolithic Period.

Which will give us a map that looks more like this:

Silbury Hill - post glacial flooding

And the reason for Silbury Hill with the flat top - very simple really!!

Silbury Hill - Neolithic Period

Now that all the critics have been silenced by the scientific logic and evidence produced to support my hypothesis we can now move on to more important aspects of this fundamental discovery - this is examined closely in the second edition out on the 16th June and the 18th Chapter of this revolutionary book will be fully reproduced on this web site to coincide with a worldwide press release.

  1. I'm convinced that Silbury hill was the first phase of building another stonehenge. Stone pillars could be pulled up the slopes of the hill then sunk into shafts that were dug behind them. Capping stones could then be pulled up and positioned on top of the pillars and accurately fitted together.
    The mound could then be removed leaving an upright stone circle with capping stones on top.

    For what purpose?

    Stonehenge Phase I was a mortuary and hospital for the sick - if this was a replacement then where is the water for the Bluestones? Groundwater would not flow to the top of a man-made hill.


  3. Hey there, I picked up a copy of the Stonehenge Enigma and read it over the weekend - I very much enjoyed it and it makes sense that the water levels were much higher, I'm no archaeologist or geologist but that seems to make so much sense in terms of moving the bluestones etc.

    I live fairly near to Silbury/Avebury and get the chance to visit fairly reguarly and for the past few years have read many books about it - and I always thought Silbury makes no sense without water surrounding it, the fact that it's built in a valley and the general shape of the landscape surrounding it (plus all the water/springs still surrounding it!) cemenent in my mind that it was very much a water based feature. (As now shown in this article too!) - In my imagination I wonder whether Silbury was built over the top of a geyser type spring where the water would rush up a narrow hole in the middle and then cascade down the sides filling the moat..

    Anyway, I look forward to reading volumes 2 and 3.

    Thank you for your comments - I'm very pleased you have enjoyed the book.

    Silbury is indeed a great mystery, Its seemed to have been constructed at a much later date than Avebury, which in turn is later than Windmill Hill. The falling water levels after the ice age would suggest this is three different phases in this areas history, with a pathway (West Kennet Ave)constructed in the Neolithic connecting Silbury to Avebury.

    There has been quite extensive excavations shafts dug down the centre of Silbury in the 20th century, none of which has found any water feature at its base. But as the excavators were looking for buried gold/tombs so it is possible they were missed!


  5. I wonder how the ridgeway tied in with the surrounding landscape back then too, perhaps it was one of the main routes through England because it was all above the water level? (I've not actually walked all of it, but the parts I have walked around Avebury and Uffington are all well above the surrounding ground level)

    I just spotted this: http://www.bbc.co.uk/news/uk-england-tyne-23779202 - Tsunami? or is what they have found a result from a large river? :)


  6. Roger

    Yes the Ridgeway would have been walked after the boats had gone in the Neolithic period and we find many 'round barrows' upon it as they were used like milestones in prehistory.

    And you're quite right many of these tsunami finds are shorelines of these rivers after the last ice age - because they are inland the only hypothesis open to archaeology is tidal waves!! Quite ridiculous if you think about it - why would a tsunami only effect a small part of the land area!


  7. Hi Robert
    It's great to find a fellow thinker for once. I'd all but given up on my hypothesis, which I published in April, 2008:


    I was hoping the place would flood before I died so that I could say "told you so". Let me know if you can use any of my material. I still have the 3D models as well.



    1. Hi Dean

      Great minds think alike !

      Thank you for the offer, I'll see if I can place them in a blog soon with acknowledgements to yourself. The case for 'Post Glacial Flooding' is just not confined to Britain as the next book in the series due out in June will illustrate it actually affected the ancient world.

      Let me have your address at robert.john.langdon@prehistoric-britain.co.uk and I'll send you a review copy of the new book and a complementary copy of The Stonehenge Enigma for identifying Avebury before me!!

      Keep the faith my friend - the truth is out there!
