Emanuel Vigeland Museum, Gustav Vigeland's not so well-known younger brother erected the building as a museum for his art in 1926, but later decided it should serve as a mausoleum, with his urn placed above the door. The main attraction in this museum with no windows is the 800 square meters fresco "Vita", (Italian for "life"), showing the human life from conception till death, but other examples of his art are also on display.
Somewhat outside the city center is a peninsula called Bygdøy. At Bygdøy, you will find two groups of museums:
The Norwegian Museum of Cultural History, a large open air museum featuring typical buildings from various periods in Norwegian history. This includes a city building that shows living conditions from the 1850s to the 1980s.
Viking Ship Museum. In addition to two 1100 year old Viking-ships (apparently the best preserved in the world), it also contains various other Viking artifacts and a Viking burial chamber, complete with ancient skeletons.
Norwegian Maritime Museum. Houses a huge collection of ships and boats and records the impact of Norway's seafarers on their own country and the world.
Kon-Tiki Museum. Displays Tor Heyerdahl's balsa raft Kon-Tiki, and Ra II, as well as some other artifacts from Easter Island.
Fram-Museum. Features the vessel Fram, the worlds first ice breaker and the last polar expedition ship made of wood, and presents a history of polar exploration (with a strong Norwegian focus!)
The Holocaust Center. is also located at Bygdøy, in the former residence of the Norwegian World War 2 collaborator and nationalist leader, Vidkun Quisling. The center houses exhibitions and provides research on Holocaust and the plight of religious minorities.
Some other museums are:
Norwegian Museum of Science and Technology & The Norwegian Telecommunications Museum. A fun and very interactive place for both children and adults. Contrary to information in the common tourist brochures this building.
Tramway Museum. Displays the history of Oslo's trams, buses and metro.
DogA - The Norwegian Centre for Design and Architecture . A thriving design and architecture centre providing areas for large and small exhibitions, conferences and meetings, activities for children, as well as a bookshop and café.
Parks
Frogner Park, with the Vigeland Sculpture Park is a large green area about 10 minutes by subway from the city center. In addition to being a nice green recreational area, it is also decorated with hundreds of sculptures by the Norwegian artist Gustav Vigeland. There is a wonderfully relaxed atmosphere here, although the sculptures are a little depressing. If your children want to climb the statues, nobody will even bother to look twice at you. There is also a cafeteria, and two museums, the City Museum of Oslo and the Vigeland Museum. If you fancy an outdoor swim, Frognerbadet is situated next to the Frognerpark with 3 pools, several diving towers and a water slide.
Botanical Garden, Located just south of Tøyen park, the garden is a wonderful and relaxing area.
St.Hanshaugen is a delightful public park on the highest hill in central Oslo. Great view of the city and surroundings.
Slottsparken (Palace Park) surrounds the Royal Palace at the top of Karl Johan street. Oslo\'s most central park is a pleasant grass covered area with majestic old trees. Wide walkways crisscross the park.
Birkelunden and Olaf Ryes plass Two cool parks in eastern Oslo, situated in the Grunerløkka, a so called Greenwich village look-alike area.
Sofienbergparken A lot of activities all day long and especially in the weekends; ballplay, pick-nick, public barbecue, specially nice area for children.
Visit Ekeberg, the steep, green hill east of centre. From the wide hairpin bend at road Valhallaveien there is a great view of the city. This point is assumed to be the background for 'Scream', Edvard Munch's famous picture.
Stensbergparken is close to Bislett Stadium. This charming park has an old church and a café on the top, and is your best bet if St. Hanshaugen is too crowdy (only a few minutes walk away.)
