Husum Nationalpark-Haus is one of several North German exhibition centres for the Wadden Sea and its fauna. This one is located by the harbor in the town of Husum and consists of two part - an exhibition room with text signs and photos, and a tank for fish and invertebrates caught in the nearby Wadden Sea.
The exhibition is not nearly as big as it looks from the outside, as only a part of the ground floor is used for exhibitions.
