Whether this is ‘case closed’ is uncertain but it does seem to offer another option to resolve the puzzle, as the Telegraph explains.
It is an archaeological conundrum that has baffled generations of experts. Just how did prehistoric Britons manage to transport the huge bluestones of Stonehenge some 140 miles from the Preseli Mountains in Wales to their final home on Salisbury Plain, Wiltshire?
The answer is surprisingly simple. The feat really isn’t as hard as everyone imagined.
An experiment by University College London found that mounting huge stones on a sycamore sleigh and dragging it along timbers required far less effort than was expected.
In fact the one tonne stone whizzed along the make-shift silver birch track when pulled by just 10 people, moving at around 10 feet every five seconds – which works out faster than one mile per hour if pulled continually, rather than in the short bursts of the experiment.
Stonehenge expert Prof Mike Parker-Pearson of UCL believes the Stonehenge stones were part of a monument that once stood in Wales which was dismantled and moved to Wiltshire. But even Prof Parker-Pearson was amazed at how quickly the stones could be dragged.
“It was a bit of a shock to see how easy it was to pull the stone,” he said.
