Agglestone Rock, also known as the Devil's Anvil, is a sandstone block of about 400 tonnes weight, perched on a conical hill, approximately 1-mile (1.6 km) from the village of Studland, south Dorset. Formerly an 'anvil' shape with a flat top, it fell onto one end and side in 1970, leaving the top at an angle of approximately 45°.
