The main features of this nave are the depth-perspective of the apse and chancel; verticality (relationship between height and length); the very high form arches (arches adjacent to the facade), fasciculated pillars and hexapartite crossings (6 arches: 2 acros torais and 4 form arches) with a closure in the center of the vault (the Rosette loses its structural function becoming sculptural). The nave's stained glass windows are from the 19th century. XV.
