Stonehenge 'complete circle' evidence found


The parch marks were seen during hot, dry weather in July last year

Evidence that the outer stone circle at Stonehenge was once complete has been found, because a hosepipe used to water the site was not long enough.

Parch marks in the grass, in an area that had not been watered, have revealed places where two "missing" huge sarsen stones may once have stood.

The marks were spotted by an English Heritage steward who alerted archaeologists to their existence.
Previous scientific techniques such as geophysics failed to find any evidence.

Historians have long debated whether Stonehenge was a full or incomplete circle, with some arguing a lack of stones in the south-west quadrant is proof it was never complete.

A scientific paper which adds weight to the "complete" theory has been published in the latest issue of the journal Antiquity.

The parch marks - areas where the grass does not grow as strongly as in other areas during hot, dry weather - were first noticed in July last year.

Susan Greaney, from English Heritage, said the discovery seemed to indicate the positions of missing stones.
"If these stone holes actually held upright stones then we've got a complete circle," she said. [...] bbc.com
