“Prior to 19th century quarrying Penhurrock was a large cairn or mound. Its piecemeal destruction led to the uncovering of numerous burials, a ‘cist shaped hole’ cut in the solid rock and a number of stone circles. The site has been built on a natural knoll, no doubt to create an illusion of size”.
