[Illustration: FIG. 1121.--Collegiate Church of St. Salvator. Plan.] St. Andrews, and the other buildings of which are modern. The church bears the marks of the period when it was erected, the latter half of the fifteenth century. It consists (Fig. 1121) of a single oblong chamber about 107 feet long and 28 feet wide internally, with a three-sided apse at the east end. There are now no windows in the north and west walls, but the south wall is divided by buttresses into seven bays, with a large pointed window in each, which, together with the three windows of the eastern apse, sufficiently light the church. The central window of the apse is larger than the others. The tracery in the windows is modern. The buttresses between the bays are bold and effective (Fig. 1122), having a broad moulded base and being enriched with canopied niches for statues on their face. The canopies on the buttresses next the apse are placed [Illustration: FIG. 1122.--Collegiate Church of St. Salvator. View from South-East.] facing one another on the angle of the buttress instead of on the face, an arrangement not easily explained. The buttresses are now finished on top with gabled pinnacles, but these are a modern restoration. The original pinnacles were, doubtless, of the late and rather stunted character usual at the period, of which one specimen survives, at the north-east [Illustration: FIG. 1123.--Collegiate Church of St. Salvator. South-West Porch.] angle of St. Salvator’s, where, however, it is little seen. Between two of the buttresses, near the south-west corner, a porch is introduced under the [Illustration: FIG. 1124.--Collegiate Church of St. Salvator. View from South-West.] window (Fig. 1123), the buttresses being slightly extended beyond the others to receive it. The porch is roofed with groined vaulting, and has a stone bench on each side, and a canopied niche on each side of the wide entrance arch. A shield at the apex bore the arms and mitre of Bishop Kennedy. The doorway within the porch has a three-sided head or arch, and the north door opposite it has a similar top. The tower at the south-west angle of the church is of the usual plain unbuttressed form (Fig. 1124) common at the period in Scotland. On the ground floor it contains the gateway to the college. Over the outer archway are the arms of Bishop Kennedy in a cusped panel (Fig. 1125), having a canopied niche on each side. Over this the tower rises to the string course under the belfry story, with no features but small loops in the wall. The belfry story has a lofty double window on each of its four sides.
