IV. In the restoration of 1866 many fragments of Anian’s cathedral were found in the walls, and were used up by Sir G. G. Scott in rebuilding the transept after what he imagined to be Anian’s design. The choir-chapel was also rebuilt as organ-chamber, library and chapter-house. The aisles also, and the central tower, were almost wholly rebuilt. Llandaff. Llandaff, though practically but a suburb of the busy town of Cardiff, still remains picturesquely environed by woods and meadows and hills and the Taff. Externally it adds one more to the endless varieties of English cathedral architecture. No central tower is here, and the position of transepts is inadequately occupied by the chapter-house on the southern side. One unbroken roof, as at Dorchester abbey church, extends for the whole length of the cathedral, the Lady chapel excepted. Its west front, indeed, is cathedral-like, now that a south-west tower and spire, in French Gothic, has been added. Internally, the absence of a triforium gives it a parochial appearance. Indeed, both externally and internally, it has the appearance rather of a magnified parish church than the seat of one of the most ancient bishoprics in the country. Nevertheless, as at Wakefield, and Dorchester, it is quite possible that, though now it is a vast oblong, 200 feet by 70 feet, it was originally a Norman cruciform church. But whether it had originally a central tower, or towers flanking the choir, somewhat after the fashion of those of the old cathedral of Como or those of Exeter, it is impossible to ascertain. The architectural record of Llandaff is incomplete, and the evolution of the ground-plan is a puzzle not to be disentangled. Of Norman work there are two sets. One is to be found in the presbytery: it consists of the east wall and its arch, and of fragments of an arch and window in the south wall. This seems to be the work of Bishop Urban, _c._ 1120. The nave was probably not completed till late in the twelfth century; the only visible remains are the north and south doorways (Transitional). It would seem that it was determined subsequently to rebuild not the whole eight bays of the nave and choir, but only the interior of them. The walls of the low Norman aisles, with their doorways and windows, were left untouched. But a new set of piers and arches carrying a clerestory were put up in place of the Norman work. It is possible that the nave was not given a triforium, because there still survived low unvaulted Norman aisles on either side of it. All this is excellent Lancet work, done between 1193 and 1229. To this period also belongs the fine west front and the vaulted vestibule to the chapter-house. Between 1244 and 1265 a little southern transept was built to serve as a chapter-house. Below, it is square, but nevertheless has a central stalk like the octagonal chapter-houses at Salisbury and Westminster. The upper story is octagonal, and has a steep octagonal roof.
