The church is built partly of a warm brown sandstone, partly of stone of a pale yellow or drab colour, the two kinds being in many places mixed so as to give the walls a chequered appearance. This may be noticed both outside and inside the building. In some of the walls the stones are used irregularly, in others they are carefully squared. The red stone is to be met with in the neighbourhood: some of that used for raising the transept walls in 1891 was obtained from a bridge in the town that was being rebuilt; and from marks on some of those stones it appeared that before being in the bridge they had been used in some ecclesiastical building, so that they have now returned to their original use. There is little ornament to be seen outside, save on the upper stage of the tower; in fact, the whole building excepting the arches of the nave and the tower may be described as severely plain in character. The college was never wealthy, hence probably it could not employ a number of carvers; then again it was not a monastic establishment, so that there were no monks to occupy their time in the embellishment of the building, carving, as monks often did, their quaint fancies on bosses and capitals. We miss the crockets and finials, the ball-flower, and other ornaments that we meet with in so many fourteenth-century buildings; but the very simplicity of the work gives the church a dignity that is often wanting in more highly ornamented structures. The small number of the buttresses in the body of the church is noteworthy; save at the angles there are only five--namely, two on each nave aisle, and one on the north choir aisle. At each of the eastern corners of the choir aisles the buttresses are set diagonally, as also are those on the northern corners of the north porch. There is a buttress on each of the side walls of the north porch, and two set at right angles to each other at each of the two corners of the north transept, and also at the south-west corner of the south transept; beneath the east window of the choir there is a small one. The buttresses at the corner of the choir project but slightly. The central tower has none, but the west tower has an octagonal buttress at each corner. The central tower attracts notice first. From the outside at the angles a small portion of the plain wall of the triforium stage may be seen, against which the roofs of the choir and transepts abut; the nave roof, however, hides all of this stage at the western face: above this face is a band of red-brown sandstone, and above this the clerestory stage. In each face are two round-headed windows with a pointed blank arch between them. There are six slender shafts to support the outer order of moulding over the two windows and the blank arch, and two of a similar character to support the inner ring of moulding over each window. At each corner of the tower up to the top of this stage runs a slender banded shaft. This stage is finished by a
