Medieval shipwreck found in Baltic Sea

Twelve shipwrecks, including some that may date back as far as 800 years, have been found by a gas company building an underwater pipeline in the Baltic Sea.

The wrecks were found along a 30 mile long corridor off the Swedish island of Gotland. It is unclear what salvage or expeditions will take place as many of them are at a depth that would require very advanced and costly diving operations.
