Vasa is the name of Swedish warship that had to be the most powerful one in the Baltic, if not the world of that time. But it sank during its first and last voyage on 10th of August 1628. Due to miscalculations in construction it managed to sail away only 1300 meters. The ship was lifted only in 1961 and preserved. Now it is the only ship of XVII century and one of the most Stockholm attractions.
