In the stage above are three round-headed windows with a shaft in either jamb and foliage on the capitals. Each of these windows, like that on the west side, and several in the other transept, has been divided by a mullion into two lights, presumably in the fourteenth century.[41] The third stage, which corresponds to the triforium within, is blank here as on the west side, and in the fourth stage are three round-headed windows, plainly recessed and chamfered. The gable, on which stands a plain cross, has been lowered, as is shown by the weathering on the tower, and its sides, after descending, take an upward turn to meet the corners. It is flanked by two lofty square turrets, which have been compared with those on the west front of Tewkesbury. They have a shaft at each angle, are pierced on each face with two round-headed openings under a round arch, with a string below running round the turret, and are surmounted by pyramidal stone caps ending in pommels and having a rude pinnacle at each corner. The end of the aisle is set back, and displays a window like the three above the door, but without the dividing mullion; and above this a round-headed niche, doubtless once a window that lighted the space over the aisle-vault; while a round arch over this niche, and a little pointed arch on the buttress adjacent westwards, carry a curious thickening of the masonry above. The arrangement of the windows here breaks the continuity of the first string-course, which, after crossing the main elevation, has to be stopped and resumed at a lower level in order to pass beneath the windows of the aisle. At the corner of the latter are more clustered buttresses, terminating below the parapet, and above them rises a plain gabled pinnacle (an addition, probably, of the fourteenth century), while another buttress, rising from the inclined coping of the aisle-wall, runs up the clearstorey.
