After initially serving as an armory, the Zeughaus was converted into the Prussian-Brandenburg Hall of Fame and Army Museum between 1877 and 1881. During the Nazi era, the building was requisitioned by the Nazi regime. It was severely damaged during the war and burned down. After the war, it was rebuilt under the direction of various architects. From 1952 onwards, the GDR regime used the armory as the central socialist history museum of the GDR, the Museum of German History. After reunification, the German Historical Museum moved in. In 2003, a modern extension was added to the Baroque building.
