In Stavanger, there are many museums but the Norwegian Petroleum Museum is especially interesting. North Sea oil has enriched Stavanger since the 1970s and today it is known as the main oil city of Norway. The Norwegian Petroleum Museum shows how oil is formed, how it occurs and what it is used for. The museum also has a well stocked gift shop and a cafe with tasty dishes. It is unmissable if you are in the area. Info available in English and Norwegian.
