Five centuries of architecture: a Roman belfry, a radiant choir, a flamboyant porch and nave, a Renaissance gateway and a somewhat heavy handed restoration, by Ballard and Lassus, in the 19C. It is the porch which draws attention with its central doorway, from the 13C. In the interior, works of art (ancient stained glass windows, a beautiful choir-grille, a 14C stone Madonna) and the tombs of Malherbe, Chardin, Van Loo, Coysevox, Le Vau, Soufflot... and other artists who lived at the Louvre.
