'I screamed' Dig reveals site of suspected lost Cornish henge

It was a grey autumn day, but Henry Stevens' tough shift digging in a field next to the A30 was about to get very exciting. Her eye was caught by something glinting in the soil and she picked up a flake of flint that had lain for thousands of years in what might just turn out to be a Cornish version of Stonehenge.

"I screamed," said Stevens, 27, a volunteer on the Castilly Henge archaeological dig. “I was so excited. I held it up to the sky and the light shone through it. Lovely.”

The flake was probably the byproduct of a Neolithic person fashioning some sort of tool. “As I work here now, I think about the people who were here before us,” said Stevens. “Why did they build this? What drew them here?

Experts and almost 100 volunteers have been on the site near Bodmin over the last month trying to work out if Castilly Henge is Cornwall's great lost stone circle.

The site is an oval earthwork with an external bank and an internal ditch, thought to have been the venue for gatherings and rituals in about 2,500BC - the same sort of time that Stonehenge was built 150 miles (240km) away in Wiltshire.
