The tower consists of a base, a main body and a crenellated and turreted roof. The base contains the ground floor. It has battered (sloped) outer surfaces. The main body has vertical walls. The limit between the base and the main body is marked by a sandstone belt course. The base and the main body are square in plan and comprise a round stair tower that projects from the southeast corner. The tower's square part is surmounted by a short setback cylindrical storey that is covered with a steep conical roof. The transition from square to round is achieved by a platform decorated with four corner turrets linked by machicolated battlements. The turrets are round and also wear steep conical roofs. The five roofs are entirely built in lapped stone courses. The southeastern turret serves as cap-house over the stairs giving access to the parapet walk (or chemin de ronde). The other three turrets are smaller and sit on corbelled bases. Each of these bases consists of a pile of five roll-moulded corbel courses. A chimney stack is attached to the inner side of the northwestern turret.
