Cranmer's Mound is a late 11th or early 12th century earthwork motte and bailey fortress, which has a later reference to Archbishop Thomas Cranmer. The low motte and the two rectangular baileys were all enclosed by wet ditches, which is part of later water management. When the site was re-used during the post-medieval period, as a prospect mound to overlook an extensive complex of fishponds and islands. 7 miles south-east is Belvoir Castle and 12 miles west is Nottingham Castle.
