Saint Catherine's Fort

Marine fort, of rock-faced limestone with tooled limestone dressings and some granite. Aligned NW to SE with 2-storey and basement entrance end at NW, centre with 3 large square gun openings in granite-faced walling each side, and SE end trilobe bastion, an open-air gun platform. Big rounded cornice all around with low parapet. Similar rounded moulding over basement at entrance end. Entrance is across dry moat originally with drawbridge to rusticated arched entry with outsize radiating voussoirs, plaque above and corbelling under cornice. Ground floor square-headed gun-opening each side, in angle to projecting square bastions. These have similar openings to basement and ground floor and small cambered headed window to first floor, while side walls have 3 square recessed small gunports on each of the three levels, commanding the dry moat. The side walls are granite faced at lower level with curved jambs and massive voussoirs to the gun openings, now glazed, and there is grey stone walling above. The end bastions are low, as built into the rising rock.

Not inspected, said to be much damaged.
