In the 9th century a watchtower was built, which was converted into a place of worship and part of a monastery. This sturdy church - Église Saint-Saveur - was constructed in the 11th century by the lord of Beaumont and has become a place of worship and pilgrimage. The church was extended with two apses, tall flamboyant crossings, a rose window, a primitive tower, a bell tower, scarlet half-timbering and a wooden spire.

This former priory church is characterized by a mixture of architectural styles. Wars, the Revolution, abandonment and multiple acts of destruction have left a deep mark on its history. The various phases of reconstruction have gradually transformed the original layout. Apart from the tower, which has retained its Romanesque style, the nave and choir, which were partially destroyed in 1612, have been remodeled.

An extension of the monks' building, the parish church, destroyed in 1804, was enlarged with a ‘neo-Gothic’ porch in 1861. Major renovations have been undertaken in recent decades: stained glass windows damaged during World War II in 1952 and a restoration of the bell tower in 2007.
