Atlanticum

Atlanticum is a maritime museum in the fishing harbor that housed a 150,000-liter seawater aquarium displaying North Sea creatures such as cod, catshark, and spider crabs. The facility now presents the permanent exhibition 'Expedition Nordmeere' with information about marine ecosystems and fishing history.

The building was originally a fish dispatch structure and was relocated in 1996 to its current location as part of the Forum Fischbahnhof development project. After the facility closed in 2013, the aquarium was transformed into an exhibition focused on marine research.

The museum demonstrates fishing practices through recreated harbor scenes and hands-on stations where visitors learn traditional knots. These displays show how closely fishing work was connected to the daily life of the city.

The museum is located in the fishing harbor and is best reached on foot or by public transit that goes directly to the harbor area. A visit works best on days with good light, since the building is historic and shows interesting architectural details from the outside.

Visitors, especially children, can make prints of sea creatures at a specialized relief wall while learning about the diversity of North Sea wildlife. This hands-on activity connects creativity with learning in a direct way.
