In 1107 the tower of Winchester fell in. At Salisbury the spire is still a constant source of anxiety, despite "a complex arrangement of iron bands and ties," which has been reinforced more than once. The tower of Chichester collapsed in 1861. There is a legend of the fall of a central tower at Christchurch Priory, and other warnings could be cited, such as Hereford, Selby, Peterborough, and Wells. [3] "Architectural History of Exeter Cathedral," by Philip Freeman, Archdeacon and Canon of Exeter (Bell), 1888. Originally these two towers were cut off, by two arches underneath, from the body of the church. But Quivil, wishing to enlarge the interior, did so by "throwing the Tower spaces into it." #The Roof# is one of the most striking features of the building, especially as it is seen from a distance. The long line of the ridge of nave and choir, unbroken by a central tower, give it a unique distinction amongst English cathedrals. The delicate cresting of fleurs-de-lis, and the pinnacles which crown the supporting buttresses obviate any impression of heaviness, and together with the long series of clerestory windows, alike in form yet differing in their admirable tracery, give a singular impression of beauty. #The North Porch.#--This was the northern entrance of the Norman church, and from the outside it is possible to trace the line where the fifteenth-century front was added to the old structure. It is decorated with seven canopied niches in the style of that period. These, however, remained vacant until 1920, when they were filled with statues, by Mr. H. Read of Exeter, representing the patron saints of England and the Allies: St. George, St. Denys, St. Joseph; SS. Cyril and Methodius; St. Vladimir, and St. Ambrose. The roof is vaulted, and on the central boss is a finely-carved Agnus Dei. Within a recess of the eastern wall are three headless figures, representing, in the centre, the Crucifixion, St. Mary and St. John standing on either side. Over the inside doorway is a niche that probably once held a figure of the Virgin. [Illustration: THE NORTHERN TOWER. The Photochrom Co. Photo.] [Illustration: EXETER CATHEDRAL--THE WEST FRONT.
