It’s easy to forget that Hamburg's zoo, 5km (3 miles) southwest of the city center, is home to some 2,500 animals, so appealing are the landscaping and architectural attractions. The Nepalese temple and Japanese garden are especially transporting, as are the animal enclosures themselves—the Tierpark was the first zoo in the world to recreate environments similar to the creatures’ habitats in the wild, separated from onlookers by pools and moats. These have been shored up a bit since 1956, when in one of the biggest “zoo breaks” in history 45 rhesus monkeys escaped from their quarters and ran wild through the streets of Hamburg.
