18th Century Ship Cannons Retrieved from Bottom of Baltic Sea

Polish explorers have retrieved three cannons from 18th century shipwrecks resting on the floor of the Baltic Sea.

An official at the Main Sea Museum in Gdansk, Poland, Iwona Pomian, said on Monday that the cannons have been identified as Swedish, bearing a mint date of 1771.  The cannons were found in the carnage of a Swedish Navy ship beneath 130 feet (40 meters) of water. 

The three that were retrieved are reportedly only a few of more than 40 cannons, and additional cargo found among the wreckage. 

Pomian added that the will museum experts around 4 years to clean and do preservation work to the cannons before they will be able to be put on display for the public.
