Salle Olga Olby (Ancienne église du Couvent des Minimes)

On the site of this former church (now the Olga Olby Hall) and the neighbouring buildings, the priory of Saint-Pierre was built in 1026 by the Benedictine monks of the Abbey of Saint Germain d'Auxerre.
The priory declined at the end of the 15th century, and in 1621 it was ceded to the Minimes Fathers. In 1629, the Minimes rebuilt the premises and the cloister as they exist today.
The façade is made of ashlar (1629).
The buildings around the cloister now house the "Pierre Lôo" day hospital.
The cloister is closed to the public except for the Heritage Days.
This former church is currently used as an exhibition and concert hall and bears the name of Olga Olby (1900-1990), a Russian painter who donated her works to the town of Decize.

It can be visited by individuals in July and August as part of a guided tour and all year round by appointment for groups.
