national museum of Luxembourg, located in the historic centre of Luxembourg city (Luxembourg) at the Fish Market (Marché-aux-Poissons). It is housed in an extensive late Gothic and Renaissance mansion. The museum has collections of Gallo-Roman art, coins, medieval sculpture, armour, and contemporary art, as well as a 25,000-volume library. There is also a special exhibit entitled “The Fortress of Luxembourg” with models.

In 1854 the Luxembourg Society of Natural Sciences established a museum that became the nucleus of the Luxembourg State Museums. The collections were moved to Fish Market square in 1922. From 1970 the earth sciences and astronomy exhibits were expanded, and in 1988 the State Museums were administratively divided into the National Museum of History and Art, which remained at the Fish Market, and the National Museum of Natural History, which completed its move to a separate location (on Münster Street) in 1996.
