Built in 1380 and 1750, it has an Italian style coffered ceiling, a pink marble chapel, a listed pulpit from 1788, stained glass windows, an organ inaugurated in 1996, and various furniture. It seems that this collegiate church has its origin in a medieval priory, perhaps Carolingian, a moment subservient to the abbey of Nantua. "Friends of the organ" will be present to explain the operation of the organ.
