About 180 feet east from the chapter house a long range of buildings extended for upwards of 250 feet in a north and south direction; but as these are fragmentary, and as the detached buildings of a monastery were not conformable to a general plan, it is needless to attempt to define these further than to point out that the upper story of the south-east building was a dovecot, the walls of which are entire to a height of about 20 feet. The range of buildings, of which the dovecot forms the end next the river, extends, in its present condition, for about 120 feet westwards. [Illustration: FIG. 633.--Cambuskenneth Abbey. West Doorway.] [Illustration: FIG. 634.--Cambuskenneth Abbey. The Tower from South-East.] The tower (Fig. 634), which is the best preserved portion of the monastery, stands near the north-west angle of the church, but is detached from it. The abbey being situated on the extensive plain known as the Carse of Stirling, probably after the Reformation the tower was found to be useful as a place of outlook over the level country around, and also, perhaps, as a place of security. The monastery was difficult of access, being almost surrounded by the river Forth, which winds here in a remarkable manner. It is, therefore, not unlikely that for the above reasons the tower has been preserved entire. It measures rather more than 30 feet square, with walls about 6 feet thick. It is groin vaulted on the ground floor, and has an octagonal turret stair leading to the top. From old plates it appears to have been finished on the top with the usual cape house and chimneys. The existence of fireplaces indicates, as above suggested, that the tower was taken possession of as a watch tower or castle, and was thus preserved. It is peculiar in being detached from the church, from which it is separated about 20 feet. The entrance to the tower (see Fig. 634) is by a narrow doorway in the south front. It has a slightly projecting porch with a high gablet, containing a niche, and is surmounted by a buttress. There are indications of buildings having been attached to the tower on the east side, but they have been of later construction than the tower, and were probably outhouses, such as are frequently found in connection with the pele towers. The finishing of the upper part of the parapet is modern. The tower is four stories in height, and is of good simple design in the later first pointed style.
