I like the Vasa Museum. You can spend the whole day. There is a film in Russian and a cartoon for children. The audio guide is available for download. You can do without a guided tour. There is a cafe and a place for a snack.
Perhaps the most famous and popular museum in the Scandinavian countries. An incredible and fascinating story of the sinking of a naval ship, as well as its rise.
We were told about this place when we were teenagers, so when we got here, the feeling was like a fairy tale. The entrance is expensive, the museum is dedicated to one ship, which can be viewed from all sides and from different floors. Information about the exhibits is very well provided (in several languages, including Russian and Chinese). It is convenient to get there.
