The oldest building located on the Unter den Linden is the Zeughaus Deutsches Historisches Museum (German Historical Museum). The Zeughaus was originally built as an arsenal for the Prussian military and construction started in 1695 and completed in 1730. The first design of the Zeughaus was by the German Baroque architect Johann Arnold Nering with later input from the German master builder and architect Martin Grunberg followed by the German Baroque sculptor and architect Andreas Schluter.
