On the banks of the River Isar, south of central Munich, is the city’s zoo: the Tierpark Hellabrunn. Just over a hundred years old, it was the most progressive zoo in the world when it first opened, with an approach that most major zoos the world over would end up emulating. Two things set it apart: firstly, the animals were arranged more or less according to their region of origin. Secondly, they were placed in environments as close as possible to their natural habitats, allowed to wander freely with moats to keep them from the public (and vice versa).
