Established in the 13th century in the faubourg then called Saint-Jean-de-Mazel, the Carmelites built their chapel there at the beginning of the 15th century. At that time, the city was under the authority of the Dukes of Burgundy whose art was at its peak. Of the chapel, only the choir remains today, the nave having been destroyed by the Gros family around 1800. Its acquisition by the City in 1969 enabled the expansion of City Hall and the library. The large window with a flamboyant Gothic-style replacement, visible from Rue de Lyon, as well as the carved stone capitals, accessible from the library’s lending room, bear witness, in a very fragmentary way, the richness of Burgundian sculpture at this end of the Middle Ages.
