The history of the royal ship Vasa is fascinating. From its sinking on its maiden voyage, through its salvage 333 years later, to where it stands today. The world's only preserved wooden ship of this size, 98% intact. The museum has exhibits on everything from life in the 17th century to how the ship was restored and the museum built where it stands today. A perfect activity on a day when the Swedish weather might not show its best side.
