the highly-decorated warship Vasa sailed from Stockholm on her anticipated maiden voyage - and sank immediately due to major flaws in her construction design.
More than three centuries later, the Vasa was rediscovered and is today the world's only preserved 17th-century ship. The Vasa Warship museum allows you to view the Vasa ship from six levels and it has been chosen as one of the 7 wonders of Sweden.
