Built from 1557 to 1559, it is adjacent to the Mission buildings. Above the entrance door, you can still see a coat of arms of the commander of the Holy Spirit, Claude Buffet (1540-1570) who directed, at the beginning of the 16th century, the hospital of the Holy Spirit in Besançon. It is possible to visit this private property by appointment by registering with the Tourist Office of Greater Besançon.
