#The Central Tower# rises a single storey above the ridge of the roof and is open inside to the top. But for small gables on the buttresses, it is quite plain up to the level of the roof ridge. Above this it contains two long and narrow Perpendicular windows on each side, of three lights each, with a transom. These windows are ornamented with ogee gables, and between them are three niches, one above the other, with canopies. The external buttresses are split up with vertical mouldings and ornamented with niches and panelling. The tower is crowned with a battlement. Horizontal string courses with gargoyles divide the buttresses at intervals. There are no pinnacles on these buttresses, and they appear never to have been finished. It is possible that it was intended to set another storey on the top of the present one, but this is merely conjecture. This tower, or rather its Perpendicular casing, for it was originally an Early English tower, is, with the western the latest part of the minster, but it is by no means the least beautiful. The English architects of the sixteenth century, if they were inferior to earlier builders in invention and vigour, were at any rate supreme in the management of towers. Their wonderful sense of proportion, their habitual use of vertical lines, and the character of their windows helped them to build what are perhaps the finest towers in Europe, and the central tower of York Minster is one of the finest of all. Even the absence of pinnacles, if it is an accident, seems to be a lucky accident, and gives this tower an unrivalled dignity and air of restraint suitable to the character of the whole cathedral. For whatever may be said against certain parts of the exterior, as a whole it is one of the most magnificent in the world. It shows best from certain points of view--from the north, for instance, or from the network of narrow streets to the south. It may be contended that the central tower is not quite lofty enough compared with the two western towers for perfect symmetry of outline; that, seen from certain aspects, it is rather square and box-like in appearance; that from no point of view are the western towers satisfactory. But the minster produces its great effect by its enormous bulk and dignity, its vast length, the variety and yet unity of its outlines, the severity and restraint of its form.
