Fort Kijkduin is a Napoleonic fortress adjacent to the North Sea, consisting of an aquarium and a historical museum. The focus here lies on its war-filled history and life in the North Sea. In both, the theme is attack and defense. In the museum, you can see how countries and their armies do and have done this. In the aquarium, you can see how fish live & survive. One thing is for sure, the CLS Revo Series will survive perfectly well in the humid environment of the aquarium with its IP67 classification!
