Greenstone platform found at Trethevy

An archaeological excavation at Trethevy Quoit near Darite has made an exciting discovery which means that our understanding of the prehistoric site will have to be reassessed.

Between 9th and 13th July, more than thirty volunteers took part in the dig, which was supervised by Andy Jones and Ryan Smith of the Cornwall Archaeological Unit.

A geophysical survey had been undertaken in the field around the monument earlier this year and recorded a number of below-ground anomalies, which were targeted through excavation.

The largest below-ground feature was positioned close to the Quoit itself and, on investigation, this was found to be a significant platform of greenstone. The material had been quarried locally and brought to the site. It was clearly an integral part of the monument.
