La Piscine, a splendid Art Deco building in Roubaix, part of greater Lille, houses the Musée d’Art et d’Industrie. It’s one of the most exciting surprises in the Nord region, housing an impressive collection of 19th- and 20th-century art. Originally a swimming pool, now an eclectic museum that I enjoyed visiting. Shall find some more images to make a set.
