Secrets of an ancient site in South East Cornwall could be revealed as archaeologists carry out a dig.

The Neolithic burial chamber at Trethevy Quoit dates back to around 3500 BC. While any human remains once deposited under the stones have long gone, other artefacts elsewhere in the field could give pointers to who visited the monument and what they did there, says the Cornwall Heritage Trust, which manages the site.

The dig is being carried out in partnership with the Cornwall Archaeological Society and Cornwall Archaeology Unit all this week; volunteers have been signed up and schools visits are set to take place.

A community open day on Saturday (July 13) will be the chance for the public to see findings from the dig and to find out more about the Heritage Trust’s work.

Children’s activities will be available and there will even be a complimentary pasty to those who attend on a first come first served basis.
