Already within the 7th century a convent, following the Rule of Saint Colomban, existed here upto the Viking raids. New monastic life flourished, when benefactor Renaud d'Orval donated land to the Abbay Sainte-Trinité in Lessay - and a priory was founded here in the 11th century.

The parish church "Sainte-Hélène", erected end of the 11th century, was the priory´s church. The nave is Romanesque, the crossing is probably only a few decades younger. Here are the vaults of the crossing.
