On display in the historic, Gothic rooms, from the 15th century used for storing the Polish coronation insignia and Crown Jewels, are the few objects from the former Crown Treasury that have survived wars and plunder, among them the coronation sword called Szczerbiec, memorabilia of the Polish monarchs and members of their families as well as eminent personages, and also those connected with historic events, along with examples of West European and Polish goldsmith's art.
The rooms adjoining the Treasury house the exhibition of arms and armour, comprising parade and fighting weapons of Polish and foreign make, dating from the 14th-18th centuries. In addition to specimens of Late Gothic and Renaissance military equipment from Western Europe, particularly noteworthy are some 17th and early 18th century armours of the Polish cavalry - plate armours worn by the hussars and the karacenas of half-heavy cavalry (pancerni). There are numerous fine objects representing various kinds of edged weapon - swords, rapiers, small-swords, and daggers, as well as sabres and karabelas. The Polish and Turkish saddles and horse trappings are remarkable for their exceptional artistic quality and historical value. The banners and standards recall the victories won on battlefields.
