In religious terms, the parish of Péone was part of the see of (Entrevaux) until it was abolished in 1798.The first worshippers in the high valley only had one place of worship, the church of Notre-Dame du Buey in Guillaumes, where the bishop preached, celebrating the sacred mysteries surrounded by priests and other ministers.The gospel was making rapid progress in the countryside and there was a need to found churches in the villages and to send priests to then.The old churches in the area were perhaps built on the sites of Pagan temples from the Gallo-Roman era. Sometimes, old headstones were used as the holy water font or the altar.
