Situated inside a brutal communist-era pavilion, the Military Museum documents the history of the Polish military from the 11th century onwards. Starting with scythes and halberds the collection includes the armour of winged hussars, sabres, muskets and cannons, as well as portraits of Polish military commanders and famous moments in their history. The unwieldy musket ‘kolowy’ is a particularly impressive effort, and surely completely useless in combat. The 20th century section features grenades, compasses and medical kits, and the upstairs is devoted to the Wielkopolska Uprising, with medals, uniforms and postcards from the era. The collection was decimated during WWII, with the only surviving item being a fragment of Wojciech Kossak's 1901 painting, The Battle of the Pyramids.
