To the west of the six bays of the eastern arm crossed a transept, remarkable for its narrowness. In the angle between it and the south wall of the choir, rose, as an integral part of the building, a smaller tower balancing the earlier great one of Gundulf, which had been allowed to remain in an almost similar, but independent, position on the other side. It has been conjectured that the lower portions of these two towers formed the transepts of Gundulf's church. This would have greatly reduced the length of its choir, while adding, to the same amount, to that of its nave. Such a theory is, however, quite untenable now, as the real lines of the transept have been traced. In 1872, when the south end of the present transept was underpinned, parts of the foundations of its predecessor's east and south walls were uncovered, and the footings of the clasping pilaster buttress of its south-west angle exposed. These showed that the transept occupied the position which we have assigned to it, and that its entire length was 120 feet, while it was only 14 feet wide. This width being so small, it is probable that the arcading of the nave was continued right up to the choir arch. There was no tower over the crossing. Of a south tower, as has been mentioned, the foundations have been found, but the only signs of it now left above ground seem to be some tufa quoins in the wall by the cloister door. Even if these traces did not remain there would be ample documentary evidence to prove that it had once existed.
