Norman stone keep

Norman rectangular great keep in weathered limestone ashlar, 14 x 12 m and 21.8 m to the battlements with corner turrets rising to 24.8 m: pilaster buttresses, a battered plinth, arrow slits low down, round-headed windows that widen with height (two-order openings with nook shafts at the top), a first-floor entrance reached by an open stone forebuilding stair, putlog holes, a corbel table and string course under a crenellated parapet round a walkable flagged roof. Hollow, with floor ledges, a roof hatch and door, window, floor and ladder sockets; heavy wear: lichen, damp and algae at the foot, run-off under sills and spouts, eroded joints and mason's marks.
