Hangar-7, Exhibition center near Salzburg Airport, Austria

Hangar-7 is a steel-and-glass ellipsoid beside Salzburg Airport, 100 m long, 67 m wide and 14.5 m high, cut at an angle at the hangar door and pierced at the entrance by two cylindrical glass towers. Its shell of 1,754 glass panels weighs 380 tonnes; the 1,200-tonne steel frame was built by Waagner-Biro. Inside, a grey ramp curves down around a projecting round glass room above a silver four-engine Douglas DC-6B with a glass nose.

Planning began in October 1999 when the Flying Bulls fleet outgrew Innsbruck Airport. Architect Volkmar Burgstaller designed the building, construction east of Salzburg Airport's runway started in January 2001, and it opened on 22 August 2003. Waagner-Biro built the 1,200-ton steel structure.

The restaurant Ikarus, on the first floor with 40 seats, has followed a guest-chef concept since late 2003: each month a different international star chef designs the menu, so the cooking style changes monthly. Under the patronage of Eckart Witzigmann, chefs such as René Redzepi and Harald Wohlfahrt have cooked here, and each episode is filmed for the ServusTV series "The Best Chefs in the World".

Hangar-7 stands on the eastern side of Salzburg Airport; the entrance is flanked by two cylindrical glass towers, and a road ramp on the south-southeast side leads to the lower level. Admission is free, and Hangar-8, the maintenance hangar to the north-northwest, is normally closed to visitors.

The collection includes fully operational historical aircraft that take off regularly for demonstration flights from the nearby airport. Visitors occasionally witness these restored planes actually flying through the sky.
