The Limburg Zoo, also known as Zwartberg Zoo, was a zoo in the Belgian parish of Zwartberg in the municipality of Genk. The zoo was private property of the Wouters family and did not receive any subsidy or sponsorship. The zoo was known for its large number of animals, which resulted from the internal breeding programme and the acquisition of abused and dumped animals from bankrupt zoos and circuses. The large number of animals, the poor state of the animal enclosures, and actions by animal rights organisations drew media attention to the zoo. In 1997 the Wouters family decided to close it; the animals were relocated to other zoos.
