If you only visit one museum on your trip to Stockholm, visit the Vasa. It’s unique, it’s fascinating – and it’s utterly stunning. The warship Vasa sank in Stockholm harbour in 1628, moments after being launched for the first time. Its wreck was discovered in the 1950s and carefully salvaged. Despite being underwater for centuries it was in remarkable condition. This is because the Great Shipworm, a hungry little mollusc that nibbles away most wooden wrecks, doesn’t like the low-salt waters of the Baltic. The experience of seeing the ship is enhanced by the intelligent design of the museum that surrounds it. It manages to bring the boat to life in a way that is fascinating for both children and adults. It’s a good idea to start your visit by watching the film (which has English subtitles) which is shown in the auditorium near the entrance. Understanding how the ship was rediscovered and salvaged makes you appreciate just how extraordinary this museum is.
