south transept facade has a matching gable made in 1883–85, in the more ornate flamboyant style. It is crowned by two statues, Saint Nicholas and a local medieval bishop, Saint Goëry. There is also a flamboyant gable over the large south window, also an elaborate flamboyant style, with curves and counter-curves. It was damaged by the 19th-century fire and was replaced. At the top is a statue of Saint Stephen, the patron saint of the cathedral. The chevet The chevet, at the southeast end of the cathedral, was built between 1503 and 1508 atop the earlier Romanesque crypt and the earlierRayonnant style chapels. It contains the apse and disambulatory, and three radiating chapels; the axis chapel of the Virgin; and chapels of the Sacred Heart and Notre-Dame of Mount-Carmel. The doorway to Rue du Vivier was added in 1889. The chapels are separated by the massive buttresses and arches which support the upper walls. The buttresses themselves are decorated with spires, which give them extra weight. The windows of the upper walls are topped with pointed arches and pinnacles, and the chevet is flanked by two additional slender towers with spires on either side of the choir, which give additional support to the structure. On the north is the Tower of the Boule d'Or or Tower of the Pomme d'Or (Named for a gilded copper apple ornament on top of the spire before the Revolution); and to south, the Tower of Charlemagne. This tower has a stairway that gives access to the terraces, triforium, and the narrow pathway around the edge of the roof of the choir. The Interior The nave The nave is the portion of a cathedral, usually at the west end, where the worshippers are seated. The nave of Metz Cathedral is noted for its exceptional height, harmony, and especially the great quantity of stained glass that entirely fills the upper walls, the largest area of glass of any cathedral. It has the traditional elevation of Gothic cathedrals of the 13th century, with three levels; an arcade of pointed arches supported by large pillars on the ground floor, 12.65 meters high; above that a triforium with windows. six meters high; above that a decorative band of two friezes with sculpted foliage and drapery; and above that the high windows extending upwards 25.5 meters into the vaults. Slender colonettes run up the walls between the windows from the
