Porlock Stone Circle is a stone circle located on Exmoor, near the village of Porlock in the south-western English county of Somerset. The Porlock ring is part of a tradition of stone circle construction that spread throughout much of Britain, Ireland, and Brittany during the Late Neolithic and Early Bronze Age, over a period between 3,300 and 900 BCE. The purpose of such monuments is unknown, although archaeologists speculate that the stones represented supernatural entities for the circles' builders.
