Bremen Cog
Reconstruction of the cog "Roland von Bremen"

Bremen cog or Bremer Kogge is a well preserved wreck of a cog dated to 1380 found in 1962 in Bremen. Today it is displayed at the German Shipping Museum in Bremerhaven as one of the main features. There are also three relatively identical Bremen cog replicas built namely Ubena von Bremen, Hansekogge and Roland von Bremen.

On 8 October 1962 during dredging operations fragments of the ship were found in the Weser River. It turned out to be the remnants of a cog that seems to have sunk during a storm flood after being drifted away from a shipyard before completion. Based on the dendrochronological analysis of the oak timber from which the cog was built the ship was dated to about 1380 AD. The search for more shipwreck fragments continued until July 1965 and yielded over 2,000 individual pieces of the ship. The fragments were transferred to the German Maritime Museum for preservation. In 1999 after 19 years of reconstruction the preservation was finished and the ship is now on display at the designated Koggenhalle of the German Maritime Museum.

The precise dimensions of the Bremen cog were 24m long, 8m in the beam and just over 4m high on the sides. These measurements would have produced an estimated load capacity of 130 tons.[1]
