The collegiate foundation consisted of a provost, six prebendaries, one clerk, and two singing boys. The edifice has undoubtedly been rebuilt or restored at the date of its being made collegiate. It corresponds in style with the numerous collegiate foundations established in the fifteenth and sixteenth centuries. The eastern apsidal termination, the stone roof supported on a pointed barrel vault, and other details point to its date and associate it with the other collegiate churches of Scotland erected in the fifteenth century. In 1544 the structure suffered much at the hands of the English invaders, who carried off the organ and bells, and burnt the timber work. [Illustration: FIG. 1144.--Seton Collegiate Church. Plan.] The stone roof of the choir was removed at some period. The masonry, however, survived, and the edifice has now been roofed in and properly defended from the weather by the late Lord Wemyss, who, along with his Countess, is buried in the choir. The broken tracery of the windows has been renewed by the present Lord Wemyss. The church was designed [Illustration: FIG. 1145.--Seton Collegiate Church. View from South-East.] as a complete cross without aisles, and with a central tower and spire over the intersection, but the nave has never been built. The portions erected (Fig. 1144) consist of the choir (with its three-sided apsidal east end), a north sacristy, a north and south transept, and a central tower and spire over the crossing. The choir is 53 feet in length by 22 feet in width internally. The exterior (Fig. 1145) is divided into three bays, separated by buttresses. There is a round-headed doorway in the central bay of the south wall, with a panel containing a coat of arms in the upper part of the wall, and mullioned windows in the other bays (including the apse), except that in the north wall at the part where the sacristy is built. The arched heads are all filled with tracery of a simple character and of [Illustration: FIG. 1146.--Seton Collegiate Church. Corbels on Buttresses.] a pattern common in third pointed work. The buttresses are of good substantial form, and each is crowned with a square, but rather stunted, pinnacle, the enriched pyramidal tops of nearly all of them being wanting. A carved corbel and canopy are placed on the face of each buttress to receive a statue, but they are now all empty. Fig. 1146 shows two of these corbels, one containing the Seton arms. The cornice of the choir is enriched with flower ornaments.
