ZOOM Erlebniswelt Gelsenkirchen, founded on April 14, 1949, as "Ruhr-Zoo", is one of the most modern zoological gardens in Germany. It was founded on a heavily shelled area in Gelsenkirchen adjacent to a port on the Rhine–Herne Canal. It initially encompassed 15.5 hectares. During its first years, there was a large turnover of animals as an animal trader, Firma Ruhe, provided them.
