Even in strictly cruciform churches, transepts were sometimes treated with a freedom which was more appropriate to the transeptal chapel. It is not unusual to find one transept longer than the other, as at Felmersham in Bedfordshire. Here, however, the transepts are not only of different lengths, but the south transept is loftier, as well as shorter, than the north, which is little more than a chapel-like excrescence from the tower. At Witney in Oxfordshire both transepts are of great projection, but the north transept is slightly longer than that on the south. Both have considerable traces of thirteenth century work; but, in the fourteenth century, the north transept was lengthened by an addition divided into two stories, the upper of which was a chapel, while the lower was probably a vaulted bone-hole. The south transept was also lengthened; and a chapel was built, projecting from its east wall near the south end. Both transepts have western aisles: that of the north transept, which stops short of the two-storied extension, contained an altar near the north end. There are traces of at least three other altars in the transepts, so that there was excellent reason for their somewhat unusual projection. At St Mary's, Beverley, an eastern aisle was added to the south transept in the fifteenth century, to provide more room for altars. The north transept already had a large chapel of two stages upon its eastern side, so that the plan was treated unsymmetrically. The tower of St Mary's at Stafford rests on heavy piers and narrow arches, and is flanked by north and south transepts. However, while the south transept, of good thirteenth century work, is rather small and short, the north transept was rebuilt with great magnificence in the fourteenth century, and its internal effect is that of a large side chapel rather than a transept. Aisled transepts are never common, even in large churches. Instances in which a transeptal chapel is aisled are even less common. The aisled south chapel at Medbourne in Leicestershire has been mentioned in an earlier chapter. Oakham and Langham churches in Rutland have large transeptal chapels with western aisles: the north chapel at Langham was removed in the fifteenth century, when the aisles of the nave were widened.
