Tower at Fort Williamsburg

The tower is set on a motte-like mound and has wide views across the estate and out to sea. It is a 2-stage octagonal tower built of brick with scribed cement render and has a crenellated parapet and a square vice tower to south. There are band courses above each floor; the 1st floor has replaced semicircular headed horned sash windows and the ground floor has square-headed openings including a doorway to north-west and another to the stair tower. Over the former, main, doorway is a stone plaque inscribed 'Williamsbourg Fort'.

The fort is roughly square with redans to the four corners and with surrounding ditches and revetment walls.

Much restored and without significant individual features. Winding timber stairs rising to single octagonal chamber at 1st floor and on to roof level.
