OSLO AIRPORT GARDERMOEN The Oslo Airport is the main domestic hub and international airport for Norway. There's quite a bit of wood used in the design of the building, which gives it a very eco-friendly feel. A lot of care and attention was put in the details of the airport and the way the it interacts with the public.
Art can be found in and around the airport. The main art on the land side of the airport, Alexis, consists of six steel sculptures in stainless steel created by Per Inge Bjørlo. Carin Wessel used 30,000 metres (98,000 ft) of thread to make the impression of clouds and webs, named Ad Astra (show above). Anna Karin Rynander and Per-Olof Sandberg cooperated in making the Marathon Dancers, located in the baggage claim area, a set of two electronic boards that show a dancing person, and Sound Refreshment Station (six are located in the departure areas), which are sound "showers" that make refreshing sounds when a person is immediately under them. Sidsel Westbø has etched the glass walls. Vebjørn Sand built a 14-metre (46 ft) statue named the Kepler Star.
CANBERRA AIRPORT
Canberra Airport serves the capital. Since it's not a major airport it was difficult to find pictures. Nevertheless, the exterior is simple and bright and the interior seems rather dark but modern. The airport also includes a large mall, Brand Depot.
2010-01-31 UPDATE : I recently was informed by a representative of the Canbberra Airport that it is currently undergoing major renovations to build a bigger and better terminal. I got a hold of some renderings for the future airport, shown below. It looks like it's going to be brighter and more colorful. It will be interesting to see the final results.
