In the Middle Ages, the monks of Nanteuil Abbey were lords of individual communes. In 1172, they ceded some of their land to the abbey of Grosbot, to build a church. Towards the middle of the 17th century, the population had increased, and a parish was created. The Saint Bartholomew church, slightly larger, was damaged by the Protestants. It was the subject of renovation in 1888–1889.
