Its origins remain unknown. Nothing remains of this primitive building, which undoubtedly served as a relay from before the 11th century between the Saint-Bénigne abbeys of Dijon and Saint-Maurice d'Agaune (in Swiss Valais).
The north side portal is the oldest element (15th century). The building has been altered several times. The typical Comtois bell tower has a so-called imperial roof, covered with glazed tiles. An exterior tower houses the staircase leading to the clock, the bells and the room of the lookout responsible for giving the alert in the event of a fire. A nave, made up of a central aisle and two aisles bordered by side chapels, precedes the choir built in 1809. A Soldats' chapel was built in 1920 in memory of the victims of the First World War. The vaulting of the whole is not uniform: groin vaults, rib vaults and ceiling. In 1970, Canon Prenel launched a major restoration, completed in 1974 with the installation of stained glass windows by the painter Alfred Manessier (1911-1993) which constitute a spiritual itinerary inspired by Saint John of the Cross (1542–1591) to the Alleluia of the rosette of the choir.
To note, various furniture elements, many of which are protected as Historical Monuments: a polychrome wooden statue of the Virgin and Child known as the Virgin of Lausanne (15th century), the high altar created by Irene Zack (1970), the 18th century organs restored and enriched with a positive in 1982, the pulpit to preach (1754), a recumbent Christ (16th century), a Black Madonna and Child known as Notre-Dame des Hermites or Notre-Dame d'Einsiedeln (1690) which is the object of a very widespread cult in Haut-Doubs.
