Baltic Sea pipeline-builders find centuries-old shipwrecks

A dozen centuries-old shipwrecks – some of them unusually well-preserved – have been found in the Baltic Sea by a gas company building an underwater pipeline between Russia and Germany.

The oldest wreck probably dates back to medieval times and could be up to 800 years old, while the others are likely from the 17th to 19th centuries, Peter Norman of Sweden’s National Heritage Board said Tuesday.
