Castle Hill is an 11th century earthwork motte and bailey fortress, founded by Roger Busli. The truncated motte encased by a wide ditch, defends a north-eastern bailey and a small northern half-moon annexe, which is possibly a barbican. Overlooking the Strafford Sands, an important crossing of the River Don, the bailey encased by a wide rampart and ditch, supports the remains of a 19th century bandstand. Now part of a public park and landscape gardening has obliterated parts of the earthwork and damaged others. 2 miles south-east is Conisbrough Castle and 8 miles north-east is Castle Hills Langthwaite.
