In the west walk is the lavatory (Perpendicular), already mentioned, and the entrance (Perpendicular) to the _dormitory_; this, like the refectory, was a long parallelogram. The foundations of the walls have been traced, and portions of a row of columns (Perpendicular) which ran down the centre of the undercroft. At the north-west angle of the cloister is the monks entrance to the cathedral. The cloister terminates nearly in a line with the third bay of the nave. Parallel with the last two, or transition Norman bays, is a narrow arched and vaulted passage, also transition Norman, of very good character, with a doorway of the same date at the western end. On the south side of this passage there is a staircase which led to the dormitory, and at the north-west angle one which leads to the triforium of the south aisle of the nave. Beyond this passage a view is obtained of the very plain _west front_, with its Norman portals and modern Decorated window. XXII. On the _north side_ of the cathedral, between the north porch and the west front, stood the “Carnerie,” or charnel-house chapel, built by Bishop William de Blois in the thirteenth century, and demolished in 1677. The crypt is still remaining, although no trace of it is visible above ground. The two transition Norman bays on this side had apparently shewn signs of weakness in the Perpendicular period, when the existing flying buttresses were erected. A third occurs between the two transepts, and close beyond it is the entrance to the _crypt_. [Plate IV.] This is by no means the least interesting portion of the cathedral, since it is unquestionably the work of WULFSTAN, and the only part of the building which can be assigned to him. In 1084 Wulfstan began the rebuilding of the monastery, and in 1094 he held a synod in the crypt of the cathedral, “which he had built from the foundation.” This was no doubt the existing crypt, which extends under the choir and its aisles. The main piers, which are solid masses of masonry, stand immediately below those in the choir. In the central division of the crypt, the vaulting is carried on three rows of pillars, with plain cushioned capitals and [Illustration: THE CRYPT.]
