M. Viollet-le-Duc shews the very close resemblance between the plans of St Just and those of the Cathedrals of Limoges and Clermont, in Auvergne. These he regards as the three most splendid and remarkably similar examples of the Gothic of the fourteenth century, and he thinks that they have probably all been designed by the same man. The Cathedral of Narbonne is distinguished by the beauty and skill of its construction. In the fourteenth century the Gothic architects had arrived at great perfection in the art of building. The various forces in connection with the vaulting had become perfectly understood, and here the architect has endeavoured to shew how accurately he could calculate them. All the mouldings are carefully profiled, and the penetrations and junctions admirably managed; but sculpture is almost entirely dispensed with, even the caps of the columns having no foliage. As a piece of architectural engineering the building is perfect, and has stood without a flaw; but it rather wants interest owing to the absence of ornamentation. It was begun on a great scale, but, owing to want of funds, only the choir has been erected. The vault is nearly as high as those of Beauvais and Cologne. The absence of decoration in the building itself is, to some extent, compensated by the richness and beauty of the tombs and monuments inserted between the piers of the choir. That of Archbishop Pierre de la Jugée is specially rich in sculpture, and still retains some fine painting. Like most of the churches in the South, St Just is fortified, and, along with the Archbishop’s Palace, formed the citadel of the city, and occupied the site of the Roman Forum. The fortifications consist in a double tier of crenellations, which take the place of the usual balustrades over the chapels, and are continued round the apse, with arched passages which rest on piers brought up from the chapels of the “rond point,” and are crowned with turrets which, as well as the connecting bridges, are all provided with crenellated parapets. These airy provisions for defence give an unusual and very singular appearance to the exterior of the apse (_see_ view, Fig. 103). In the twelfth century Narbonne was a place of great importance, but, owing to the silting up of the harbour in the fourteenth century, its commerce and revenues were greatly diminished.
