"Ubena von Bremen" - Hanseatic Cog

Cog replica from Bremerhaven

During harbor extension work in 1962 the Hanseatic cog from Bremen was discovered in the mud of the River Weser. It is the only remaining, relatively well preserved ship wreck, which depicts the North European art of shipbuilding.

The “Ubena von Bremen” is a reconstruction of the Hanseatic cog from the 14th century found in the mud of the River Weser in 1962. Up until 1965 efforts were made to find still more pieces. In the National German Maritime Museum the sensational finding was reconstructed piece by piece (more than 2000 individual pieces), measured and over a period of 15 years was preserved for generations to come in a preservation bath (a 800.000 liters mixture of water and polyethylene glycol). Since May 2000, after the preservation period, the original cog is on display in the German Maritime Museum. Much is known about the activities of the Hanseatic League through conveyed documents and reportings. However still today authentic documents are missing about the cogs, their construction and rigging. Researchers and interested parties could only rely on old city seals or passed on drawings in order to solve the puzzle.
