Motte-and-bailey castle
In the village of Barneville, behind the church, is the remains of a Motte-and-bailey castle which was transformed into a calvary that was called "Mallet's Mound" after the Mallet family of Carteret and Barneville mentioned in 1066. The square church tower from the 15th century has a parapet over a blind arcade which was besieged by the English in September 1499.
