Formerly a wheat mill, then used for hydroelectricity production, this building now houses the municipal campsite. But its walls also hold a piece of history: in 1859, they witnessed the birth of Firmin Bouisset, the illustrious poster artist behind the famous advertisements for Biscuit LU and Chocolat Menier, among others! We invite you to discover his life and career, and to admire his works at the Espace Firmin Bouisset in Castelsarrasin.
