Middleton Castle is an 11th century earthwork motte and bailey fortress, founded by William of Ecouis. The large motte, is encased by a wide ditch and to the east is a sub rectangular bailey, with the remains of its encasing rampart and ditch. Excavations of the ploughed out bailey shows, that the castle was also occupied during the early 12th century. A mile north-east is Middleton Towers and 4 miles south is Wormegay Castle.
