La Piscine (French for «the swimming pool») is a museum of art and industry, located in the city of Roubaix in northern France. It is more formally known as La Piscine-Musée d’Art et d’Industrie André Diligent or Le musée d’Art et d’Industrie de la ville de Roubaix, but its common name derives from the fact that it is housed in a former indoor swimming pool, with a notable art deco interior.
