At the south-west angle of the cloister court was the staircase which led to the upper floor (see Plans). The latter (see Fig. 745) has been very greatly altered, and has been divided by cross walls and partitions, so as to form a dwelling-house. A square tower has also at a late period been added on the exterior next the south-west angle (Fig. 747). It would appear, however, that formerly the apartments, although situated on the [Illustration: FIG. 747.--The Abbey of Inchcolm. View from South-West.] first floor, were arranged in the usual manner. The dormitory occupied the east side, and had direct communication with the choir. The refectory was in the south range, and the pulpit from which one of the monks read during meals is yet preserved, with a few steps in the thickness of the wall leading up to it (see Fig. 745). The pulpit is also seen projecting on the exterior in Fig. 747. The west side was probably occupied by the lay brethren. A large fireplace, corbelled out on the exterior, was built in the east wall of the latter department, as shown in Fig. 754. There was an exterior door to the garden from the cloister walk on this side. The nave, tower, and original choir were, without doubt, the earliest parts of the edifice. The two-story cloisters did not at first exist, as is apparent from the exterior window of the south wall of the choir, above referred to. Probably there was then an ordinary cloister walk running south from the principal doorway of the church, from which a one-story building would enter on the east, according to the usual plan, containing sacristy, chapter house, &c. Remains of a stone seat, which exist along the east wall of the ambulatory, may indicate the original position of the chapter house; and there are distinct evidences of alterations in the east wall, to the south of the existing chapter house. At first the refectory would probably be on the ground floor of the south range, and the dormitory may have been on the first floor over it. The above would be the arrangement of the monastery when built about the beginning of the thirteenth century, soon after it received the gift of Wester Aberdour from Allan Mortimer.
