Nunney Castle is a small, French style castle surrounded by a deep moat, built for Sir John Delamare in 1373. A veteran of the Hundred Years War, Sir John would later become Sheriff of Somerset.

During the Civil Wars (1642-51) Cromwell's men used cannon to blast a great hole in the north wall of the castle, forcing the garrison to surrender. The badly damaged wall finally collapsed in 1910.

Due to its small size and ruined interiors there is not a lot to see at the castle, but, surrounded by its moat, it is an attractive feature in a pretty village.
