Here in Vienna is the so called "Heeresgeschichtliches Museum" which means something like "Military History museum". One part is also the Navy History of the austrian-hungarian Period
Great Pictures! Thanks for sharing! Isn't there a Lancaster bomber rear turret in that museum? The Lancaster was salvaged from an Austrian lake in the 1950s in almost pristine condition. It was up for sale but nobody wanted it so it was eventually scrapped, save for the rear turret.
