There was a strong maritime tradition with thousands of vessels that were lost along the Swedish coastline. Researchers estimate that there are a total of 40,000 known wreck positions in the Baltic Sea. Sweden is in the unique position of not having any woodworm to destroy the wrecks as well as low-salt levels and preservation qualities of the water in the Baltic Sea.
Even the Swedish Tourist organization has recognized this and incorporated info about wreck diving in the country.
