When we examine the details of the architecture we can express nothing but the greatest admiration. The whole of the south wing of the front belongs to the last quarter of the twelfth century. The lowest stage of all (for there are six stages, divided by horizontal strings) is blank; the next three are late Norman. These have in the lowest stage in each of the two divisions an arcade of seven tall lancets; in the next above are four broader arches, each containing two small lancets beneath; in the upper one is a large window, under a round arch of four receding orders, with a blank lancet on each side. In the north wing, it should be noted, the late Norman work was carried up one stage higher than on the south. The upper stages are Transitional in character, but they carry on the idea of the Norman design below. Here we see first an arcade of four trefoiled lancets, of greater depth than those underneath; while the uppermost stage has a large pointed window, with a lancet on each side, and above each lancet a quatrefoil in a circle. The arches of the window and lancets are highly enriched with carving. Below the parapet is a good corbel table. The fourth and sixth stages are further covered with admirable diaper panel-work. The octagonal towers at the end of the southern transept, of which that to the west is larger than the other, have three more stages, the central one having small, deeply sunk trefoiled lancets; the other two, large plain ones; the uppermost tier of lancets being open. A singular effect is produced in the third stage from the top by the lancets being divided in the centre by the main shaft that rises from the ground at the angles of the tower. On the south and east these shafts are not perfect.
