In the forebuilding, on the level of the second floor of the keep, remain to be mentioned the robing-room, ante-chapel, and chapel. They are placed in the lower tower of the forebuilding over the lodge, vestibule, and lower chapel, and were entered only from the keep, through the mural chamber already described. From this chamber a passage, only 2 feet 5 inches broad, lies in the wall over the outer doorway, and from it a loop opens over the staircase, outwards. This passage, 17 feet long, ends in two small doors, right and left, one entering the robing-room, the other the ante-chapel. Originally this was the only way into the chapel, and a very stout person could scarcely have reached it. The Plantagenet princes, though mostly big in the bones, were rarely corpulent. The robing-room is over the lodge. It is 10 feet by 7 feet, vaulted, groined, and ribbed; the ribs are of plain roll section, and there is no boss. They spring from nook shafts at the four angles. There are loops, or rather small windows, of a foot opening to the west and south, flanked by small columns. The ante-chapel, 16 feet by 13 feet, has an arcade of two arches in the north and south walls, and a loop in the north-east space, converted into a small door, so as to give a separate entrance. In the east wall an arch of 8 feet span opens into the chapel. It springs from coupled columns, flanked on each face by two others, and the arch has a chevron moulding. The floor was of timber, and rested on five beams. The roof is vaulted, groined, and ribbed, and the moulding a roll with a band of dog-tooth. The chapel is 14 feet by 13 feet. It is peculiar in its position, being placed over the base of the entrance stair, instead of, as at Middleham, at its head. It also has an arcade of two arches in the north and south walls, with nook shafts in pairs at the angles behind which, from a corbel capital, spring the ribs of the vaulted roof. These are of a roll section with a band of the dog-tooth ornament, and a central flowered boss. There is a small east window, and also south of it a piscina with a trefoiled head and projecting basin, now broken off. This seems a Decorated addition. There are two loops in the south wall, and one in the north near the east end, and in the other north bay a cupboard. The floor was of timber, resting upon four joists.
