Göteborg - Säve Depot
June 9, 2013
This is an extrordinary museum situated in a cavern complex carved into the rock. Built in the early 1950s for the Royal Swedish Air Force F9 Wing the rock shelters are nearly 30 metres below ground level. They are located at Säve Depot opposite to the current Göteborg City airport terminal at the site of the former military air base. Since 1999 the Aeroseum Foundation has been utilisiing the shelter for a large collection of mostly former Swedish Air Force fast jets and helicopters.

The museum is open Monday to Sunday 11:00 to 18:00, but please visit the official website (see above link) to confirm these times. My brief visit was during the Aero Show.
