In the military section of Gothenburg’s airport is a facility from the Cold War era.
Built between 1950-55 is a subterranean hangar that was kept secret until the 1990s.
In 2005 it was converted into an aviation museum, and is a seriously cool place to check out military aircraft.
There’s a collection of helicopters and Swedish-made fighter jets and bombers like the Saab 37 Viggen and the Saab 35 Draken.
