The #Central Tower.#--The present central tower is noble in proportion, and forms a fitting and harmonious summit to the whole group. It must needs be of a very different character from the old Norman tower, of which no trace now remains; and was most probably of the usual type, low and square, and surmounted by a short pyramidal spire. The existing structure may be attributed to Bishop Booth and Prior Richard Bell, about 1474, when the letter previously quoted was written. Externally the tower is divided into two storeys. The lower portion contains, on each side, a pair of two-light windows, glazed, each divided by a transom, and their heads having an ogee label crocketed and finished with a tall finial also crocketed. Between and on either side of these windows are panelled pilasters and brackets carrying figures. The lower and upper stages are divided by a narrow external gallery running round the tower, and protected by a pierced, embattled parapet. This is known as the Bell Ringers' Gallery, and certainly adds greatly to the effect of the tower as a whole. The upper stage, which is much less lofty, has also two two-light windows on each face, surmounted by crocketed ogee label mouldings and finials. These lights are louvred. The whole is surmounted by a deep open-work parapet. On each angle of the tower are two buttresses, which are decorated with panelling and canopied and crocketed niches containing figures. The interior of the tower or lantern is remarkable for the gallery which runs round it, which is reached from the roofs of the nave and choir transepts by doors. It rests on corbels, each alternate one being carved with grotesque heads, and is protected by a parapet pierced in quatrefoils. The four doorways are ogee-headed, with crockets and finials. There is strong evidence in the construction of the present tower that it was the original intention to surmount it by some other erection, probably a spire. Each interior angle contains strong and massive squinches which are of no constructive use at present, and must have been originally inserted to carry some superstructure. The buttresses at the angles are also carried up to the parapet, which would seem to point to the same conclusion. Why this project was never carried out cannot be said, but probably it would not have added to the artistic effect of the tower. The belfry contains a peal of eight bells. [Illustration: The Central Tower.] The #East Front.#--The circumstances which led to the removal of Carileph's apses and the erection of the eastern transept have already been referred to. The present east end is divided into three bays by massive buttresses, each of which contains three lofty lancet windows separated by smaller buttresses. Over all, and in the gable, is the famous large rose window. The north and south ends of the transept are finished with the tall pyramidal pinnacles erected by Wyatt.
