Five centuries of architecture: a Romanesque bell tower, a High Gothic chancel, a Flamboyant porch and nave, a Renaissance portal... and a somewhat heavy-handed restoration by Baltard and Lassus in the 19C. It is the porch that catches the eye, with its central portal, from the 13C. Inside, works of art, ancient stained-glass windows, a fine choir-grille and the tombs of Malherbe, Chardin, Van Loo, Coysevox, Le Vau, Soufflot and other artists installed at the Louvre.
