The western chamber was certainly vaulted, the corbels whence sprung the ribs or vaults remaining at the four angles. The other two chambers were probably also vaulted, some trace of the angle corbels remaining. A special rib seems to have shut off the south-east angle, probably to give head-room for the staircase doorway. A doorway led from the south to the western chamber, of which the south jamb remains. Probably these chambers were vaulted in two bays, but of this no indication is left. All are lighted by loops, each loop is about 2 inches broad, and 6 feet above the ground, and is placed in a round-headed stepped recess, splayed from an internal breadth of about 4 feet 6 inches. Of these loops there are six. One in the north wall, opening from the north chamber; three in the south wall, of which two open from the south chamber, and the third from the west chamber, which has also two others in the west wall. The south-east angle is occupied by a well-staircase 11 feet 8 inches diameter, which rises to the roof, communicating by a short lobby with each floor. The only access to the basement was by this staircase from the first floor. The first or main floor was divided by the cross-wall into a larger east (_e_) and a smaller west chamber (_d_), and a shelf or set-off reduces some of the walls by a foot, and enlarges the inner area accordingly. At this level also the walls contained several mural chambers. The main, and indeed the only entrance to the tower was on this floor in the east wall, about 10 feet from the ground. The doorway, a plain rounded arch of 5 feet 4 inches opening (_f_), led into a passage of 6 feet breadth, opening direct into the eastern chamber. There was no portcullis, and the only defence was a stout door, barred. In the south wall of the passage a small doorway led into a chamber in the east wall, 6 feet wide by 14 feet long, and which has a loop in its outer wall, and no doubt opened by a doorway, now broken down, into the east chamber. On the north side of the doorway, but not communicating with the passage, the north-east angle of the building is occupied by a second mural chamber 14 feet long by 9 feet broad, also vaulted (_g_). In the north wall of this chamber is a fire-place with a concave back, and at the east end is a loop. It was entered from the east chamber by a doorway, now broken down, in its south wall, and this door led into a small lobby, cut off by a cross-wall from the chamber with the fire-place. A third mural chamber is entered from the larger room by a small door in the south wall. This opens into a passage 2 feet 6 inches broad, and 33 feet long, lighted by a couple of loops in its south wall, and terminating in a small chamber about 8 feet by 4 feet, which occupies the south-west angle, and was lighted by a loop in the west wall.
