Built from the 12C to the 16C, it has both Romanesque and Gothic features. Its façade, with its three portals, offers precious Flamboyant finery. Inside the spacious and light three-aisle nave, without a transept, do not miss the Romanesque columns, the splendid stained-glass window of the Adoration of the Magi and the marble frieze depicting the signs of the zodiac. Around the chancel, Flanders tapestries illustrate scenes of the life of St Maurice (16C).
