Cley Hill is a prominent chalk hill west of Warminster in Wiltshire, rising to 244 metres, owned by the National Trust since 1954. It features a large univallate Iron Age hillfort, two Bronze Age bowl barrows, and medieval strip lynchets. The hill served as a tribal boundary marker between the Durotriges and Dubunni, whose distinctive coinage concentrations meet at the chalk escarpment. In 1812, antiquarian Sir Richard Hoare excavated one barrow but found it had been previously looted. The hillfort is connected to nearby settlements by a network of field systems and farmsteads.
