Interior of Cathedral The Cathedral has an inside overall length of nearly 440 feet and a breadth of about 200 feet in the transept. It comprises: The great nave, composed of six bays with aisles and posterior chapels (14th century). The transept with aisle and three bays in each arm. The choir, composed of four bays and double aisle. The seven-sided apsis with ambulatory, on which open out seven pentagonal radiating chapels. The most striking features of the interior are its great height, the few points of support, and the simple character of the latter. [Illustration: GREAT NAVE. (_height 140 ft._) (_Cliché LL._)] The Great Nave (_photo opposite_) The great nave, which is about 48 feet wide, is nearly 140 feet high, and is the second highest Gothic vault in France (that of the choir of Beauvais Cathedral is about 156 feet high). Few edifices exist in which the solid parts have been so reduced in favour of the spaces.
