This is one of the few collegiate churches in Scotland which were entirely finished and still remain unaltered. It is of a cruciform plan (Fig. [1260]) and has a small western tower entering from the church by a narrow doorway. The building measures internally from east to west along the south side 62 feet 1½ inches, and along the north side 64 feet 6½ inches by 18 feet 5½ inches in breadth, and the walls are 14 feet 3 inches high from the floor to the wall head. The measurements over the transepts are 64 feet 5 inches from north to south, by 15 feet 10 inches in width (inside measure). The tower is a small apartment of 6 feet 11 inches by 4 feet 9 inches.
There are two entrances, one being at the west end of the south wall (Fig. [1261]). It is round-arched with a bead and hollow moulding and a rude string cap. The other is a plain lintelled doorway in the north transept.
In each of the north and south walls of the transept there is a traceried window, the one to the south (Fig. [1262]) having three lights and the other (Fig. [1263]) two lights. The walls are of considerable thickness, and the tracery is well recessed (Fig. [1264]) and gives, in consequence,

a massive and substantial appearance to the otherwise well designed windows.
The other windows are simple and such as are found in castles and minor churches. That adjoining the entrance to the south transept is interesting from having its sconsion arch (Fig. [1265]) neatly constructed so as to die away upon the splay. In the west gable there are two narrow windows. The lintels of these, instead of being level, lie at the same angle as the slope of the gable, and just a little below it (Fig. [1266]). A similar kind of window may be observed at Dunblane at the east end of the room over the north aisle of the choir. The transepts each open from the church by a segmental arch (see Fig. [1265]), springing from splayed

responds, having moulded bases and caps (Fig. [1267]). From the floor to the top of the caps measures 8 feet 2 inches, and the arch has a rise of 2 feet 10 inches, in a width of 11 feet 9½ inches. It is difficult to say how the roof at this part was finished originally. The present roof at the east end is of considerable antiquity, having timbers about 6 inches square, but the part resting on the transept arch is comparatively modern. That it was not finished as it is now is almost certain, as there appears to have been a gable over the arch, separating the transept roofs from the main roof.
