In 1617 the whole benefice was annexed to the Bishopric of Dunblane, in order to provide a suitable support for the bishop. On the overthrow of Episcopacy, in 1689, the revenues were annexed to the Crown; and now the sole relic of the great regality of Crosraguel is the small plot of ground enclosing the ruins. The abbey buildings (Fig. 813) have been of considerable extent, and still comprise, besides the remains of the church and cloisters, with the usual ecclesiastical buildings surrounding them, an outer court to the south-west, with a picturesque gatehouse, pigeon-house, and other domestic structures. There was also an eastern courtyard, which contained the abbot’s hall, and the adjoining tower or keep, the infirmary, &c. The whole precincts were enclosed with a high wall, which included an extensive garden. The small burn which flows along the south side is believed to have fed fish-ponds in the neighbourhood. The church (Fig. 813) is a simple oblong structure, consisting of choir and nave, without aisles and without transepts. It would appear, however, from excavations carried out by the Ayrshire and Galloway Archæological Association, that the original church of the thirteenth century contained a north and south transept, some traces of the foundations of which were disclosed. A few other relics of this earlier church are observable in the base of the western part of the nave, in traces of the jambs of the western doorway and the jambs of the north doorway of the nave; but the remainder of the church has been entirely rebuilt, chiefly on the old foundations. It is thought by Mr. Morris, who illustrates and describes the abbey in the publication of the above Association, that part of the older building is traceable in the wall between the choir and the sacristy, where vaulting shafts exist on the sacristy side in such a position as not to be available in the present structure (Fig. 814). From this fact he forms the deduction that these shafts and the wall they are attached to are part of the original church. He is further of opinion that the part of the ancient church [Illustration: FIG. 813.--Crosraguel Abbey. Plan.] [Illustration: FIG. 814.--Crosraguel Abbey. Sacristy, looking East.] which he supposes has survived at this point formed the model on which the restored building was designed. From the character of the design, [Illustration: FIG. 815.--Crosraguel Abbey. Interior of Choir.]
