Immediately to the rear of the chateau is the Cathedral of St. Pierre, ancient as to its foundation, and grand as to its general effect, both inside and out, though its exterior is marred by its uncompleted towers. Lofty, but of heavy proportions, St. Pierre de Nantes would, at first sight, appear to offer much that goes to make a satisfying ecclesiastical building. As a matter of fact, it fails in many particulars to realize any ideal which we have come to admire. The western facade is more indebted to the rich and reasonably ornate portals for its undeniable impressiveness, than to the gable of towers, which have crumbled exceedingly from the effects of wind and weather, rather than of great age, since they date only from the fifteenth century. The choir rests on the remains of an older church, hardly to be seen to-day in any appreciable evidence, in that restoration and rebuilding have been so extensively carried on. The windows throughout are but weak decorative elements, and lack tracery and glass of a decorative quality, an obvious detraction in any great architectural work. The south transept shows indications of four successive periods of construction, and contains the best glass in the church; otherwise it is severely plain. The interior is by no means as incoherent as the exterior, the height of the nave, one hundred and thirty feet, giving an otherwise unapproachable grandeur; though this admirable dimension is qualified to no small degree by a triforium of a luxurious florid growth, little in keeping with the other attributes of firmness and strength. The chapels throughout are bare and uninteresting so far as their altars or decorative embellishments are concerned,--what they may be at some future time, if the _Art Nouveau_ gets a foothold in church decoration, is fearful to contemplate. Paintings, none too common in French churches, are here somewhat in excess of customary numbers, though, as to quality or interest, in no church in France can they vie with those of the great churches of Italy or Flanders.
