Vasa Museum
Galärvarvsvägen 14, Djurgården
The Vasa Museum is without exception the most unique in Stockholm, and maybe the world, making it the perfect cultural activity (kids love it too). The entire museum is dedicated to a warship that sank in the harbor on her maiden voyage in 1628. The wreck lay on the ocean floor for over three hundred years before an intrepid scientist—who had heard the tale of its sinking—finally located its position in 1961. Because the water is brackish, the boat was miraculously preserved, making it the only ship of its kind in the world today. The museum—which was constructed around the boat, which is 95% original—takes you through the entire narrative of the doomed vessel, from the initial design and construction to the sinking and subsequent excavation (make sure to catch the short and fascinating film).
