‘A fresh theory on how Stonehenge was built has been tested out by a group of experts and enthusiasts.
Gordon Pipes, of the Stonehengineers group of scientists and archaeologists, has suggested that levers may have been used to move the giant stones.
They have tested his “stone-rowing” theory which involves a 45-tonne stone being levered on a track of logs.
“It’s akin to rowing a boat, weights can be picked up with levers using body mass and balance,” said Mr Pipes.’
