Lowe Hill is a 12th century earthwork motte and baileys fortress, possibly founded by William de Warenne. The eroded motte, is partly encased by a ditch and the two north-eastern baileys lay in-line, dropping down the hill. Encasing the baileys, are traces of low banks and outer ditches but the earthworks have been mutilated by landscaping. A third in-line terrace, is just the result of levelling to accommodate a Victorian bandstand. A mile south-east is Sandal Castle and both castles are mentioned in a royal edict of 1324. Although there exact relationship is unknown, it seems likely they controlled the River Calder together. Lowe Hill, which was by tradition destroyed by a great wind, is now surrounded by trees and hedges, so is best viewed in winter.
