Long ago (1626), Gustav Aldolphus commissioned a war ship to be the best in the world. On August 10th, 1628 she set sail into Stockholm bay, started to list, and immediately sank. For 333 years she sat at the bottom of the bay.
In 1956 they confirmed they had found the Vasa and the salvage phase of the restoration began. Amazingly, 98 percent had been preserved by the cold waters of Stockholm bay. The masts at the top of the museum illustrate how tall the ship was and the 2 percent missing.
