The North Sea Museum is the greatest aquarium in the Northern Europe. At the North Sea Museum you can learn everything there is to know about life forms in the Northern Sea. The museum/Aquarium opened for the first time back i 1984. Unfortunately a violent fire in 2003 destroyed the newest part of the museum and killed one of the main attractions, the huge ocean sunfish, but now the reconstructions are finally over and the museum is once again open to the public.
