Restalrig Collegiate Church.

Pier and Arch Ribs.

This building is a hexagon on plan (Fig. 1424), measuring 29 feet in internal diameter, and stands about 3 feet from the south wall of the church, against which the angle buttresses have impinged.

On each of the three sides facing towards the south there is a window, now built up, each of which has a very flat four-centred arch, and contains three cusped lights (Fig. 1425), divided by two mullions. The section of the jambs and mullions is shown in Fig. 1426. The roof is vaulted (Fig. 1427) with ribs springing from a central pier, which has a filleted roll towards each angle (Fig. 1428)
