In 1770, it was an abbey of reformed Benedictines. The Saint-Jean district, around the Arroux gate, north of the city, seems to have been a site for making terracotta and glass. Coroplath pottery workshops, including that of Pistillus, were located following the discovery of mussels. In the whole of the city and on the site of the monasteries of Saint-Andoche and Saint-Jean-le-Grand were discovered furniture dating from the fifth century.
