Following the 1848 revolution the new city garrison was built which now houses the Heeresgeschichtliches Museum. The four exhibit halls cover the Thirty Years’ War and Ottoman Turks, the Napoleonic Wars and the two World Wars. Temporary exhibitions are held in a small exhibition hall. The exhibits include trophies from the Turkish Wars, paintings from the Austro-Prussian War and the Gräft & Stift convertible in which the Archduke Franz Ferdinand and his wife were shot dead. Although landlocked there is even a section covering Austria’s Naval Power which includes the remains of the only Austro-Hungarian military submarine ever built.
