This church, built between 1437 and 1517, is a masterpiece of Flamboyant Gothic architecture. A large fan-shaped porch with five gables adorns the ornate façade, the central door of which features lovely Renaissance panels. Inside, look out for the organ case (1521), trimmed with Renaissance woodwork and supported by marble columns by Jean Goujon. The beautifully carved spiral staircase comes from the church's rood screen.
