In the Museum, the following permanent exhibitions are on display:

• Historic interiors of the 17th and 18th centuries;
• Ancient European and Polish armament,
• Sanctuary of Marshal Józef Piłsudski
• Gallery of Polish Painting and Decorative Art (with works by such artists as P. Michałowski, J. Kossak, J. Brandt, J. Chełmoński and J. Malczewski).
