Modern Polish art, military paraphernalia and decorative art fill the rooms in this functional pre-war building situated by a major intersection west of the Old Town. You can buy a ticket for all floors, or just one for the 20th-century art separately. There on the top floor, focus falls on the Mƚoda Polska and Grupa Krakowska movements, where works by Józef Mehoffer, Tadeusz Kantor, and Stanisƚaw Wyspiański highlight their importance in the cultural life of the late 19th and early 20th centuries.
