"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 they were provided by an animal trader.
Today the park is owned by the City of Gelsenkirchen via GEW – Gesellschaft für Energie und Wirtschaft mbH, (society for energy and business), a holding of municipally owned concerns.
After 2004 the park was enlarged to the present size." - (en.wikipedia.org 12.04.2022)
