There's a lot to discover at the Hagenbeck Zoo, everything from aardvarks to zebras, but there's one thing visitors won't see: animals behind bars. That may not seem like such a big deal today, but in 1907, when the zoo opened, its design was revolutionary. In fact, most contemporary zoos owe a huge debt to a family business that began as something more like a circus.
The Hagenbeck Zoo marked its one-hundredth anniversary on May 7 with ceremonies celebrating its legacy of innovation -- and Hamburg mayor Ole von Beust inaugurating a new tropical aquarium. There visitors can get up close, if not personal, with alligators, anacondas and a host of other reptiles.
