This former watermill, documented as early as 1089, was initially used as a fulling mill before being converted into a flour mill in the 19th century. Its operation ceased on December 31, 1974. Since then, the building has stood as a significant heritage landmark, marking the industrial and riverine history of the Vilaine Valley.
