The west chamber, 55 feet by 21 feet, has in its south end a window recess 7 feet broad, in the east wall of which a door opens into a mural chamber 14 feet by 9 feet, with a loop to the south and a fireplace in the east wall. In the west wall of the great chamber is a window recess 5 feet wide, commencing at the floor level, and there are three doors. That at the north end opens into a chamber, 22 feet by 9 feet, in the west angle, with loops to the west and north. From this opens a passage in the north wall 17 feet long, which ends in a chamber 11 feet by 5 feet; chambers and passage have loops to the north. Near the centre of the west wall of the great chamber a door opens into another mural chamber, 22 feet by 14 feet, with two loops to the west and a fireplace in the east wall. Another door leads, by a curved passage with a loop to the west, into the south-west staircase. In the great cross-wall is a door near its north end, and in each of its faces two large fireplaces, now walled up. In the north wall is a high window or recess of 8 feet opening. The main gallery, though it threads the wall nearly all round, lies at different levels, and at one point is stopped. It is entered from the two staircases. That at the north-east gives off two branches, of which one rises by fourteen steps, with a loop to the north, and enters a passage in the north wall 16 feet long, having a loop to the north, and to the south an opening, now blocked up, into the great chamber. The passage ends in a chamber 18 feet by 8 feet, in the north wall of which is a loop, and near it a deep recess for a garderobe; and in the south wall is what seems to be the mouth of a gallery threading the cross-wall, where, however, it would be stopped, or very much reduced, by the shafts of the fireplaces. The other branch from the north-east staircase rises by six steps, when it gives off a branch to the east of nine steps, which lead to the roof of the upper tower of the forebuilding. The main passage then curves and rises ten steps more, in all sixteen steps, when it enters the substance of the east wall, where it is 60 feet long and 4 feet 7 inches broad, and has a door to the east, opening on the middle tower of the forebuilding, and a loop, and opposite to these are two openings in the west wall, which formerly opened into the great chamber, and now are blocked by the brick vault. The passage then turns and lies for 67 feet in the south wall. In its east end is a loop; in its south wall, there 10 feet thick, a door opening upon the roof of the lower tower of the forebuilding. In the same wall are two, and probably three loops, opposite to two of which seem to have been openings into the great chamber. The third is much broken. In the inner wall is a recess, probably the mouth of the cross-wall gallery. At its west end the main gallery descends twenty steps to reach the south-east staircase. From this staircase, at twenty
