Park housing wool-monkeys and other species. It is located in the nature park of Mountain and Forest and proved popular with visitors and primatologists alike, leading to subsequent expansions. In 1976, gorillas were introduced to Apenheul Primate Park, with the first gorilla baby being born three years later. This was only the second healthy baby that had been born in captivity in the Netherlands and the third in the entire world. The baby was raised by its own mother, which remains a rare event.
A major setback occurred in 1981 when the cabin in which Apenheul Primate Park was burned to the ground, killing 46 monkeys. The building was subsequently replaced.
