New theory on Stonehenge mystery
Experts believe the stones may have been levered into place
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.

Mr Pipes, from Derby, combined his interest in prehistory and his skills as a carpenter to test his idea.

The method is said to require little effort and be just as efficient whether uphill, downhill or on level ground.

Many theories have been put forward for the engineering of Stonehenge, including the belief that the stones were dragged or rolled into place.

Mr Pipes is planning more experiments on Salisbury Plain next summer in an effort to prove his suggestion.

They will involve attempts to move two blocks, weighing 10 tonnes and 40 tonnes, half a mile in a day.
