Planckendael is a zoo, located on the grounds of Planckendael castle in the village district of Muizen, in Mechelen, Belgium. In 1956 the Royal Zoological Society of Antwerp (KMDA) bought the Planckendael estate in order to acquire a larger space for animals than what they owned: the city zoo in Antwerp. Planckendael hosts exotic animals like rhinos, bison and various antelope species.
