#The North Side# of the exterior of the nave differs from the south in several particulars. Thus, on the south the aisle buttresses are crowned by lofty pinnacles having at their bases niches, in some of which statues still remain. These pinnacles appear to have been originally connected with the wall of the nave by flying buttresses, traces of which still exist, both on the walls and the pinnacles. In Hollar's engraving, in a later print in Dugdale's "Monasticon" (1817), and in Willis's "Cathedrals" (1742), these buttresses are represented as existing, but the accuracy of the pictures in these books cannot be trusted. It is possible that a beginning only was made of these flying buttresses, and that when it was decided to place a wooden vault on the cathedral, they were discontinued as being unnecessary. At any rate, there are no pinnacles to the aisle buttresses on the north side, and, consequently, no flying buttresses. The plainer style of the north side was perhaps owing to the fact that a great part of it was concealed by the archbishop's palace, yet at the present day it is certainly more beautiful than the south. It closely resembles the exterior of the beautiful nave of Beverley Minster, and for simplicity and delicacy of design could hardly be surpassed. The bays are marked by plain aisle buttresses, terminating in three-cornered caps, with a battlement of cusped stonework ornamented with finials behind them. The buttresses of the nave are plain narrow bands of stone topped with small pinnacles. The roof is low pitched; the only other decoration is given by the uniform tracery of the windows and by a crocketed gable above each of the windows of the aisle.
