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]).
