Wikipedia: The Deutsches Schiffahrtsmuseum (German Maritime Museum) is a museum in Bremerhaven, Germany. It is part of the Leibniz-Gemeinschaft. The main museum building was opened on 5 September 1975 by then-president Walter Scheel, though scientific work already had started in 1971. In 2000, celebrating the 25th anniversary of the museum, the Hansekogge, a ship constructed around 1380 that was found in the Weser river in the 1960s, was presented to the public after undergoing a lengthy process of conservation in a large preservative-filled basin.
The museum consists of the building planned by Hans Scharoun as well as several museum ships in the Old Harbour of Bremerhaven, including the Seute Deern windjammer and the Wilhelm Bauer U-boat.
Wikipedia "Bremerhaven is the seaport of the free city and federal state of Bremen, Germany. It forms an enclave in the state of Lower Saxony and is located at the mouth of the River Weser on its eastern bank, opposite the town of Nordenham. Though a relatively new city, it has a long history as a trade port and today is one of the most important German ports, playing a crucial role in Germany's trade."
