The Polish Army Museum covers Polish military history from the early medieval period to the Second World War, with a collection of uniforms, weapons, armour, and standards. The outdoor exhibition, spread across a courtyard, includes tanks, artillery, aircraft, and armoured vehicles from both World Wars. The sheer variety and size of the collection rewards anyone with even moderate interest in military history.
The museum is adjacent to the National Museum on Aleje Jerozolimskie, making it easy to combine both in a half-day. The collection's strength lies in the medieval and early modern periods — the hussar armour and winged cavalry equipment are particularly impressive.
