This 12th-century tide mill features remarkable Renaissance decorative elements (dormer windows, modillions, and sculptures of Abelard and Heloise). Initially a seigneurial and then monastic property, it changed hands in 1380. Renovated in the 18th century and enlarged in the 19th, it ceased operation in 1921. Listed as a historic monument in 1933, it was transformed into a restaurant before becoming a cultural space managed by the municipality since 2007.

Real racing boats are often moored here. Lots of speed, little comfort.
