Craig Rhosyfelin

 By Robert John Langdon

The Stones of Stonehenge: the Preseli Component (Press Release)

'Perhaps one of the greatest mysteries surrounding Stonehenge is the origins of the stones themselves. How did bluestones from the Welsh Preseli Mountains become the construction material for the site of Stonehenge built some 5,000 years ago? In recent years there has been renewed interest in this question and it has sparked a review of the theories concerning their origins. Were the stones transported to Wiltshire by glacial processes during the Last Ice Age or are they the result of an epic feat of unprecedented engineering and transport by our prehistoric ancestors?

Professor Mike Parker Pearson of Sheffield University is leading a collaborative project involving universities from across the UK in looking at this enigma. Their work has brought them back to Preseli in search of the quarries and sites that may be the start of the longest journey for megaliths anywhere in prehistoric Europe.

This year fieldwork will look at two bluestone quarry sites, a possible dismantled stone circle, and potential Neolithic settlement.'

Mike may have found the site of the Stonehenge bluestones, but he still is unaware of how they got them to Stonehenge - fortunately for him my book has given him a simple and comprehensive answer - a boat.

Craig Rhosyfelin at the time of the Mesolithic

Our study have concluded that the water levels around the quarry in 8500BC was so high that the site became and island - this is perfect for moving the stones directly to the Stonehenge Car Park site which itself was also flooded from the high groundwater levels from the ice age.

How Craig Rhosyfelin may have looked from the Western Shoreline looking at the island and quarry, during the Mesolithic period.

  1. Excellent reconstruction pictures - how high is the water?

  2. Stuart

    About the same level as Stonehenge at the same Mesolithic Period about 90m (would you believe!!) High falling to 75m at the end of the Neolithic.


  3. The finding of Rhosyfelin as the origin for much of the Stonehenge rhyolite debitage was funded by the Constantine XI Palaeologos Research Fund not by any government or university grant
    and independantly discovered by Drs Ixer and Bevins (working jointly).
    The work on the origins of the Stonehenge bluestones rides alongside any archaeological studies rather being part of one.
