It was founded on December 19, 1894, it has 155 buildings, located on 140 thousand. m². The museum has exhibits from Norwegian villages and cities, mainly from the period from the 17th to the 19th century, but there are older objects, such as the stave church Gol stavkirke, which was built around 1212. It consists of two main parts: The open air museum and Exhibitions. Personally, I recommend the open air museum, which enchanted me tremendously. Lots of beautiful wooden houses that you can enter and see their furnishings. The stave church is breathtaking. You can feel like in the old days. The guide are in almost each building and tell a story of the family member inhabiting this house in a very interesting and accessible way. It is certainly a very fun way to learn about fabulous Norway and its people and the culture.
Definitely must see when you are in Oslo.
A good place to spend time with children.
