In the corner between the south aisle and the transept is the Perpendicular #Lady Chapel#, three bays long from east to west, and two in width towards the south. Its windows are three-lighted. They terminate in the obtuse arches of their time and have their heads filled with tracery. At about half its height each is divided by a transom or horizontal mullion, beneath which the lights have cusped heads. The chapel was originally vaulted, so is well buttressed, which the aisle walls are not. The north aisle wall has its bays marked by flat pilaster-like buttresses, and the southern has still less support, for the similar buttresses rise only to the original level of the ground, which is now cut away for a few feet along the side of the church. #The North Transept# is in the Early English style. Flat buttresses with offsets halve the sides and flank the end. The high gable, with three circular windows and flanking pinnacles, is the work of Sir G. Scott, who rebuilt it, in place of the low, commonplace one that had replaced it about seventy years before. He also raised the roof to its original pitch. The occurrence of blind arches between the windows here is to be noticed, making continuous arcades of which the heads are carried by single shafts. The windows in the northern bay of the west wall were all inserted by Scott, who found only dilapidated blind arcades there, and the doorway in its present form is also by him, he having found the old entry very ruinous. The east side used to be almost entirely hidden by Gundulf's tower, and is still slightly concealed. It has therefore no windows except in the clerestory, and some bays even of this have none.
