The North Sea aquarium is established in fortress Kijkduin since 1996, open to the public for 363 days per year. In the beginning, it was the first aquarium in the Netherlands where visitors could walk through a twelve-metre-long underwater tunnel where you can experience the sea under water. The theme of the aquarium is since the opening entirely focused on the life in the North Sea. Because the aquarium is equipped in two beeches with several small aquariums, it creates a good image for example, the tide, seaweeds, the life of an eel and the sable colors of rays. In mid-2014 a partial replacement and upgrading of the sea aquarium has started. Not only the North Sea is mentioned, but also the fish migration to the Wadden Sea is discussed. Fortress Kijkduin is located at the place where the North Sea and the Wadden Sea meet.
Visiting our aquarium is an exciting and educational adventure, where you can see not only fish but also touching the fish.
The history of the fortress, its residents and the environment, are the centre of the museum.
