The origin of the monastery is unknown. The priory church already existed in 1117, when the church and its belongings were given to the abbey of La Chaise-Dieu. The priory, which contained twelve monks, fell into complete decline in the 15th century following poor management. At the end of the 16th century, the monks of Saint-Maur reestablished monastic discipline there and restored the church and the convent, ruined by the Wars of Religion. Of the 12th century church, the main apse and the north apsidiole remain. It was completed in the 14th century by the construction of the nave. The church was originally to have three naves. Only one remains, rebuilt on the plan of the middle nave. By a particular layout, the main apse is extended by a narrower and non-concentric apse. A chapel to the south was to complete this set. The apse of the sanctuary, vaulted in the bottom of the oven, being very low, it was necessary, to unite it to the bay of the choir through the second hemicycle, to resort to a particular construction: the large hemicycle has no vault. perfect hemispherical; to reduce the descent, the vault was abutted on a few foundations established above the triumphal arch. The ornamentation consists of plants, protruding heads, real or hybrid animals, scenes of characters. The door opening on the western facade is in the style of the 14th century. A steeple was erected on a square base, behind the gable, and was absorbed into an octagon.
