Lanercost Prior's Tower is a four storey medieval stone fortified tower, with an adjoining two storey range to the west. Extensively remodelled in the 16th century by the Dacres, when a large fireplace was built on the first floor of the west range (now known as Dacre Hall) and new windows inserted in the tower. In the outer courtyard is Lanercost Vicarage Tower and a mile south is Naworth Castle.
