chapel, 14 feet by 13 feet, which occupies the south-eastern angle of the building, and is so placed that the altar could be seen if desired by each person who entered the keep. In its north and south walls are arcades of two arches, divided by a pier carrying two nook shafts and a third shaft in the centre. In the south-east arch is a loop, and opposite to it a cupboard. In the east end is also a loop, placed in a recess flanked by two shafts. The floor of this chapel is one step above the vestibule. The ceiling of both was flat, and of timber. Beneath chapel and vestibule is the vault already described. The walls of this part of the forebuilding are from 2 feet 6 inches to 5 feet thick. From the vestibule a doorway, the second, opens in the north wall. This has a segmental head, and is original, but it has been reduced in breadth, probably when the basement door was opened, by the insertion of new jambs. It opens into a vaulted passage, 6 feet wide and 5 feet long, being the thickness of the north wall of the lower tower. It is occupied by three steps and a landing, from which four steps ascend into the middle vestibule. This is a chamber 25 feet long by 15 feet broad, having a modern roof and two modern windows in its east wall, which has been in part rebuilt. On the left, on entering, is a Tudor doorway, and above it a square-headed window of two lights, of the same date. This opens into a mural chamber already described, and thence into the first floor of the keep. A large arch of relief is seen above in the wall, and it is probable that there was always a door here.
