A geophysical survey earlier this year in the field around Trethevy Quoit in Cornwall, southwest England, recorded a number of below-ground anomalies which were targeted through excavation.
     The largest hidden feature was close to the Quoit itself - 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, and will fundamentally alter our understanding of the prehistoric site. The findings will soon be reviewed and published.
