Vasamuseet, Stockholm

In 1628, the highly-decorated warship, Vasa sailed from Stockholm on her anticipated maiden voyage and sank. However, three centuries later, in 1961, Vasa was discovered and salvaged, and is now the world's only preserved 17th-century ship. It has now been converted into a museum. The cleverly constructed museum allows you to view it from six levels. The history of the ship is documented with slide shows, movies and exhibitions. Information is available in 10 different languages. Opening hours: September 1 to May 31 10a-5p, Wednesdays 10a-8p; June 1 to August 31 8:30a-6p. Closed: December 23-25, January 1.
