Castle Hill is possibly a mid 12th century earthwork motte and bailey fortress, founded by Thomas de Cuckney. It is thought that the castle was never completed or slighted after the Anarchy, in the reign of King Stephen. The low motte, is partly enclosed by a wide ditch and the bailey now supports St Mary's church, which has destroyed any internal features. 5 miles south-east at Clipstone is King John's Palace and 6 miles west is Bolsover Castle.
