The basement is on the ground level, which is about 5 feet below the exterior ward. Above it is a first floor, which in the body is occupied by the great hall, above which is a second floor containing the chapel and upper hall. Above this is a third floor. The divisions of the wings are less lofty. The north contains six floors, the south five. There are five well-staircases in different parts of the building. Two ascend from the ground level to the first floor and there stop. Two others commence at that floor and ascend to the roof, supplying the intermediate floors, and another commences half-way up the height of the hall, threads two walls as a gallery, and finally rises as a well-stair to the roof. There was thus a ready access from the first and upper floors to the battlements in case of danger. _Basement._—In the body are three chambers placed crossways, east and west, side by side, all 23 feet long, the central 14 feet wide, the others 15 feet. The vault springs 14 feet from the floor, and in each, at the east end, is a large arched recess, high up, narrowing to a loop. At the springing line of each vault is a row of strong corbels, evidently to support a floor, a sort of windowless entresol. These lower chambers communicate by doors, and in the south wall of the most southern is a recess or cupboard. The outer doorway, 6 feet wide, at the level of the ground outside, is in the north wall, and is closed by a stout door, within which the passage descends eight steps. In the same wall is a well-stair, which ascends from the basement to the first floor, and there stops. In this, half-way up, is a door into the entresol over the northern chamber, from which level the stair is continued to the first floor. The entresols over the other two chambers were reached by ladders. The whole range clearly was intended for stores, in case of a siege. From the north and south chambers doors open into the basements of the two wings, also vaulted. The north, the prison, is 18 feet by 12 feet, with a high and narrow loop to the west. In its upper part is also a small door, from the adjacent entresol, which may have opened upon a similar floor above the prison, or may have been an opening to look down into it. In the left wing is a vault 20 feet long by 12 feet 6 inches broad, and only 8 feet high. This was reached from the adjacent chamber in the body, and contained the well. From this chamber, opening in the south wall, is a well-stair, which rises 10 feet to an entresol, and thence proceeds to the first floor. This entresol, also vaulted, was 18 feet by 12 feet. There is a fireplace and cupboard in the north wall, and in the south a small loop, a mural garderobe, and the door of entrance. From it a rise of 14 feet leads to the first floor, which is thus 24 feet above the basement.
