In 1956, Anders Franzén located Vasa outside Beckholmen in Stockholm. In the same year, diving began at the wreck site. The date that the Vasa broke the water's surface in 1961 was April 24, a few minutes after 9 in the morning, and the whole world watched.
There are many dates and times circulating and it is probably because the preparations went on for several years underwater.
Tunnels were dug under the ship to get the wires in place and it was lifted in eighteen stages to shallower water, closer to land. This mainly took place in 1958-59 and is usually also counted as salvage.
