Ashton Keynes Castle is a large 12th century earth ringwork and bailey fortress, founded by the Keynes family. Occupied until the 13th century, the low platform is encased by a wide ditch and supports the remains of a rampart that contains a drystone wall. To the west, is a square inner bailey and the south an outer bailey, both are outlined by low mounds, ramparts and ditches that were once wet. 6 miles north is Cirencester Abbey Gatehouse and 13 miles west is Beverstone Castle.
