[Illustration: FIG. 357.--Dundrennan Abbey. Monument in North Transept.] The smaller details of the eastern part of the building are greatly destroyed. The sedilia and what seems to have been a fine monument in the choir are broken in pieces. A door has been formed in the north and south side walls of the choir leading into the east aisle of the transepts. There are evident additions made, probably during this century, when the [Illustration: FIG. 358.--Dundrennan Abbey. Plan and Details of West Wall of Chapter House.] piers of the tower were rebuilt. The doorway into the south transept aisle (Fig. 356) is distinguished by a large trefoiled head, enriched with small nail head ornaments similar to those in the west doorway, but there [Illustration: FIG. 359.--Dundrennan Abbey. Exterior of West Wall of Chapter House.] is some doubt whether this is not a restoration. It will be observed that the section of the piers of the nave and transept, and also the piers of the crossing (see Fig. 351), bear a close resemblance to those of Sweetheart Abbey. But the forms here are earlier, the fillet on the outer angle being absent at Dundrennan, though present at Sweetheart. In the north wall of the aisle of the north transept, and in a round arched recess (Fig. 357), lies the sculptured effigy of a knight wearing a suit of chain armour, and with legs crossed. This is said to be the [Illustration: FIG. 360.--Dundrennan Abbey. Ornaments over Windows of Chapter House.] statue of Alan, Lord of Galloway, who was interred in the abbey in 1234. There seems also to have been a fine monument in the choir, and numerous portions of cusped and carved work are to be seen piled up in the nave, which may be fragments of this or some other ruined structure of the same nature. The cloister garth is on the south side of the nave, and measures about 105 feet by 102 feet. The walls surrounding the cloisters are for the most part old. In the north-east angle is the ancient doorway to the nave, and in the north-west angle a more modern doorway. On the east [Illustration: FIG. 361.--Dundrennan Abbey. Interior of West Wall of Chapter House.] side, adjoining the south transept, is the slype from which a wide door (doubtless modernised) leads into the transept. To the south of the slype stood the chapter house, which must have been a very beautiful building, measuring 51 feet from east to west by 34 feet from north to south internally. From some fragments of shafts which remain, and from the responds against the west wall, it appears to have been vaulted in three spans from north to south, with four bays from east to west, but the vaults have now entirely disappeared. The front wall next the cloisters, however, fortunately survives (Fig. 358).
