Two towers flanked by a square stair turret give movement to the facade. The right side in Flamboyant style dates back to the 16C, whilst the left side (16C-17C) is in Renaissance style (Roman arches, ionic pilasters, balustrade roofs, caryatids and antique statues). Inside, a 13C nave, Renaissance organ cases, 16C stained-glass windows. Notice the two canvas paintings by Quentin Varin, the master of Nicolas Poussin, and a beautiful entombment.
