The cathedral church of Rochester is, as has been already said, a very small one, and we must not expect to find in it the grandeur and impressiveness that great size often confers. As a whole, too, it is not remarkable for beauty, though special parts may claim to possess this attribute. Its chief claim to attention is its excellence as an example of the gradual additions and successive alterations made to and in old buildings during the long periods of their existence. In different parts of the fabric specimens can be seen of almost all the noteworthy variations of style that appeared in English ecclesiastical architecture from the Early Norman to the Perpendicular period. Some opinion as to the merits or demerits of various restoring architects during the last three centuries may also be formed in it, for a very considerable amount of their work remains in evidence. Many features of the building are indeed remarkable in other respects, but we are probably correct in saying that, as a whole, it is, to students of architecture, chiefly historically interesting. #The Ground Plan# is of the double cross form, frequent in buildings of this class. The nave and choir both have aisles, but those of the choir are walled off from it. The main transept is aisleless, but the north and south choir transepts have each an aisle, or small chapel, on the eastern side. Beneath the whole eastern part of the church extends the magnificent crypt. The total length of the building is 305 1/2 feet, of which 147 1/2 feet belong to the eastern arm. The main transept is 120 feet long, the choir transept 88 feet. [Illustration: PLAN OF ROCHESTER CATHEDRAL] #The Nave.#--After passing beneath the great west doorway, through its new richly-hinged doors, we descend by a flight of four steps into the nave. On the inner side of the doorway arch are found a fine cable moulding, occurring also on its outside, and the billet moulding, of which the omission is so noticeable there. In the blind arcades that decorate the nave end inside, we see, besides plain mouldings, specimens of both the zigzag and the billet. The two upper arcades are so abruptly cut by the great Perpendicular window as to make most conspicuous the fact that this is a later insertion.
