Okehampton Castle is an impressive stone motte and bailey fortress, founded by Baldwin de Brioni. The Norman motte with its rock-cut ditch, supports an 11th century two storey square keep, to which a rectangular block was added in the 14th century. The bailey is entered through inner and outer square gatehouses, with a narrow barbican passage in-between. Inside there are the remains of lodgings, kitchens, a chapel, a hall and a solar. The castle, the largest in Devon, stands against the steep banks of the River Okement, with originally wet defences on the other sides. 8 south-west is Lydford Castle and 19 miles south-west is Launceston Castle.
