Built in the XI and in the XII centuries, Notre-Dame-sur-l’eau Church is a jewel of the Romanesque Normand style.

The Romanesque Notre-Dame-sur-l’eau Church was erected around 1020 by Guillaume de Belleme. Its name comes from its situation at the edge of a ford of the Varenne. At the Church: villeins, nobles and important dignitaries stopped off on the road between Paris and the Mont-Saint-Michel. Guillaume le Conquérant (William the Conqueror), Henri II who often stayed in Domfront stopped at the Church ; Saint-Louis says prayers and gives offerings. Even Louis XI renowned for his avarice, was generous. Unfortunately, pillaging followed havocs during the Hundred Years War.
In 1826, the Church is close to be demolished, and 10 years later, an engineer not very enlightened knocked down 4 bays of the nave (more than 30 metres with the aisles)  to build a road towards Mortain. In 1889, the Beaux Arts (Fine Art) list the building. The Second World War does not save it: an air raid, in 1944, hits the nave and the bell tower, but does not demolish the Church totally.
After many renovation stages, the Church could conserve its disposition in Latin cross-shaped.
