Patrimoine culturel
Plundered in 1793, its restoration began in 1839 thanks to the Duthoit Brothers who worked on it. It is one of the three major buildings of the Picardy flamboyant gothic art. The chapel is classified as a historical monument.
Testimony to the flamboyant Gothic art of the 15th and 16th centuries and the taste for decorative sculpture. Remarkable high vaults decorated with hanging keys. (Guided tour, twinned with that of the Hospice Chapel and that of the belfry).
