Pirton Castle is a 12th century earthwork motte and baileys fortress, founded by Ralph de Limesy. The damaged oval motte supports a rampart and is partly encased by a wet ditch. The large ditched eastern bailey, contains the 12th century parish church of St Mary and to the south, encased by ditches, are two attached enclosures. These enclosures, along with the bailey are the remains of a Medieval fortified village, which may stand on Roman and Anglo-Saxon earthwork foundations. 3 miles north-west is Higham Gogion Castle and 6 miles south-east is Wymondley Castle.
