This genuine brick fortress is entered through a finely carved Flamboyant-style canopied porch. The interior is striking: the chancel is enclosed by a rood screen made of lace-like stonework and adorned with magnificent statues. The fresco of the Last Judgment, crowned by a monumental organ, is a masterpiece of 15C art, while the 16C great vault marks the pinnacle of Quattrocento art.
