As it stood in 1540
The shape it held in its prime.
A squat, cylindrical three-storey stone drum tower sits centrally on a broad, curved stone bastion with a sloping scarp rising directly from tidal water. The tower is built of light grey squared masonry with regularly spaced rectangular and angled gun/windows and a low, flat roof. The bastion has embrasures and a narrow quay/moat at water level; a low range of red-brick service buildings abuts the tower to one side.
