The arms and armour gallery, planned by Alfred Messel as a Late Gothic hall, is one of the museum’s original period rooms. The historical collection of weapons has returned here with the famous finds from Tannenberg Castle, which was destroyed in 1399. The world of knights and mercenaries comes to life with the exhibited helmets, tournament equipment in addition to firearms, swords and spears. Alongside stained glass and sculptures, original pieces illustrate the development of suits of armour. They are arranged chronologically on a runway extending upwards towards the ceiling as if in a fashion show, demonstrating that “plate iron clothing”, like its siblings made from fabric, kept pace with the developments and caprices of contemporary styles.
