Today Bremerhaven is part of the state of Bremen but is a city in its own right. This is complicated somewhat by the fact that the "overseas port" of Bremerhaven belongs directly to the city of Bremen, which is located some 50 km farther up the river Weser
Bremerhaven has only a few historical buildings, and the high street and city centre are almost exclusively post-war. The main attractions for tourists are the German Emigration Center (since August 8, 2005) and the German Maritime Museum (Deutsches Schiffahrtsmuseum) in the historical harbour with many museum ships such as the Type XXI U-boatWilhelm Bauer, the Seute Deern (a three-masted sailing vessel), and the Hansekogge, a vintage ship dating from 1380. The Lloyd-Werftshipyard is renowned for building and renovating large cruise liners, for example the Norway. The fishing port also houses an aquarium (the Atlanticum). The zoo reopened on 27 March2004, after a lengthy renovation. It features Arctic wildlife, both terrestrial and marine. Attractions include the Klimahaus, simulating travel adventure along the 8th line of longitude.
Every five years Sail Bremerhaven is held, a large sailing convention that attracts tall ships from all over the world. The last time it was held was in 2005, coinciding with Sail Amsterdam.
