The capital of Norway, Oslo sits on the country’s southern coast at the head of the Oslofjord and is known for its green spaces and museums. Many of these are on the Bygdøy Peninsula, and that includes the waterside Norwegian Maritime Museum and the Viking Ship Museum, with Viking ships from the 9th century. The Holmenkollbakken is a ski-jumping hill with panoramic views of the fjord and a ski museum.
