Fort. Late C18, with some additions of C19 and 1914/18. Limestone rubble basement storey and walls to battery, sandstone rubble walls at ground floor level, bomb-proof stone roofs, formerly slated. Roughly triangular on plan, with long gatehouse and barrack rooms along north east side (landward). Gatehouse and barrack rooms are single storey on battered basement, central segmental-headed gateway with brick dressings, loops along base of barrack rooms, facing inwards to defend the gate bridge moat. On the inner side, the barrack rooms have window and door openings with flat heads with keystone and voussoirs, rooms with vaulted brick ceilings. Stone paved ramparts to seaward sides, with 3 large reinforced concrete gun emplacements for very large sea-firing guns. Ammunition hoists and crew shelter appended to these. Older emplacements still exist on the west side. The ramparts are in rubble, but of small blocks and roughly laid in courses. Ancient monument no. 831.
