Hard to believe, but Altona and Hamburg were two rivals. Now Altona is part of Hamburg (a nice,…read morecharismatic part), but I guess there still was a need to have its own museum. And I must say, well done guys!
Small, but very informative museum, revolving around Elbe and everything which comes with it: shipbuilding, whaling(thank God it's in the past), fishery, sea trade, port and so on. A message is clear: the river is a key to regions past and the future.
There's a beautiful collection of figureheads occupying the whole room. Also a hall dedicated to Schleswig-Holstein, Helgoland island in particular.
This museum is very similar to surprise Museum für Hamburgische Geschichte (Hamburg Museum), but smaller. It has a few things, which its bigger brother doesn't have: the whole interactive section dedicated to kids - Kinderolymp and a restaurant, Vierländer Kater, a house in the house, replicating typical Northen German tavern of 18th century. The restaurant itself worth visiting, great concept!
