This church is located on the site of an ancient priory attested in 1069. At that date, the knight Amaury, son of Geoffroy de Gometz, built a church, established canons there, then gave it, in 1074, to the monastery of Saint-Pierre de Bourgueil, with the consent of his overlords, Gui Ier de Montlhéry and his brother Hugues de Châteaufort.
