The _Gatehouse_ is placed near the centre of the south side of the castle. It was an oblong building, and formed the west end of a block, of which the hall and withdrawing-room formed the eastern part and remainder. It was composed of a passage between two walls, of which one remains, and is 6 feet 6 inches thick and 45 feet long; the outer 10 feet being outside the curtain. The portal is gone, but the spring-stone remains of the inner doorway, 3 feet 7 inches broad, and recessed 8 feet 6 inches within the inner front. The vault of the passage, about 10 feet long, rested upon three bold ribs, of which the springing-stones remain, and beyond which was the outer gate, of which a part only remains. There was an upper floor, and if the rubbish were cleared away the plan of the gatehouse would be visible. The walls seem Norman, but the ribs, vault, and fittings are probably insertions of the Decorated age. The _Hall_ was poor. It was on the first-floor level, and had a floor above it, and, therefore, a flat ceiling. The basement is composed of three vaults placed transversely, with flat, slightly-pointed arches. The doors are towards the court, and one chamber has a small Tudor fireplace, in a corner. Each had a loop in the outer end, and in the ends of two are mural garderobes in the substance of the curtain. The hall was not above 12 feet or 14 feet high. In its north side is a round-arched recess, probably the original entrance, by an outer stair; and near it a fireplace. In the south or curtain side are two good late Decorated windows of two lights, rather flamboyant in tone, with plain exterior drips. Above these is a step, or ledge, for the floor of the upper room, and two windows, not directly over those of the hall. There is no very decided evidence of a _Chapel_. The _Kitchen_, probably, was near the north-east end of the hall, and against the east end of the curtain. The withdrawing-rooms were at the east end of the hall, and extended into _Clifford’s Tower_, a fine bold drum of 30 feet diameter, which caps the south-east angle of the ward. This tower seems to be of Decorated date, and the base and part of the wall original; but it has been almost rebuilt, probably with the old cut stones, in the Tudor period, to which belong its numerous square-headed windows. Part of it was taken down in 1763.
