This is the only Protestant church in the Champsaur and it witnessed the dark period that followed the Revocation of the Edict of Nantes in 1685. Today, with the religious wars firmly in the past, this building is a place of worship and assembly for the valley's Protestants.
Prior to 1685, there were three Protestant churches in the territory, in Saint-Bonnet, Orcières and Ancelle. At that time, when the Duke of Lesdiguières, Jean-François de Bonne, was extending his rule over the Champsaur, Protestants represented a significant proportion of the population. Since this major figure was also the leader of the Protestants, forced conversions were common. But when Louis XIV decided to revoke the Edict of Nantes, all over France pastors were hanged, shot and sometimes sent to the galleys, and Protestant churches were destroyed. In 1789, freedom of religious practice was finally restored.
In the valley, it was not until 1834 - and a ministerial order allocating the sum of one thousand francs for this purpose - that a new church for adherents of the Reformed Church was constructed. But by 1880 the building had become too small and a new church, inaugurated on 26 May 1886, was constructed on its present site, provided by Mr Victor Cesmat.
In 2003 significant restoration work was carried out by the municipality on the entire building.
