Gardermoen is one of the most beautiful airports I have ever seen. Especially after seeing the same white, tent like airport buildings over and over everywhere around the world this place was like a huge architectural statement. The combination of wood, metal and glass, the use of big spaces, the ease of orientation and of course smiling officers... Everything was very welcoming and relaxing.
When you are done with all of the three museums even if you are feeling deadly tired you have to walk up the hill and visit the Viking Ship Museum. The museum houses three ancient viking ships in almost perfect condition uncovered from burial grounds at the end of 19th and the beginning of 20th centuries. Hard to believe that they are not replicas. Fascinating... I have to say I skipped the Norwegian Folk Museum and took the ferry back to the city to use my time to visit the Oslo Opera House. As another architectural wonder of the city and the home of The Norwegian Opera and Ballet the building looks like a glacier slowly sliding to Oslofjord. You can climb up to it's roof from the raked facade and watch the city from there. Another very impressing beautiful building making the city look like an open air art and design museum.
