Subscribe to Naked Science - http://goo.gl/wpc2Q1 Every other Wednesday we present a new video, so join us to see the truth laid bare... Stonehenge, England's most mysterious ancient monument, on a site older than the Pyramids of Ancient Egypt. 85 massive stones, some weighing more than 40 tonnes, stand guard on a remote and wind-swept plain. Why is it here, what is it for, how was it built? The answers are lost in the mists of time. Myth links Stonehenge to England's mysterious druids, Celtic priests said to have practiced ritual sacrifice. What we do know is that some of the rocks at Stonehenge were transported more than 200 miles across the waters of England's widest tidal estuary. Naked Science demonstrates how these stones could have been carried such a vast distance, and raised into place, using just the primitive technology possessed by Ancient Britons almost 5000 years ago. And, for the first time, the film employs modern forensic investigation techniques to examine human skeletons found near the site and recreates the face of one man who may have worked on the construction of this astonishing, ancient structure.
