The "Tiergarten Schönbrunn", Vienna, was founded in 1752 and is the oldest still existing zoo.

A zoological garden, zoological park, or zoo is a place where many different species types of animals are kept so that people can see and watch them.

Modern zoos try not only to be for people's entertainment, but for education, research, and the conservation and protection of animals. Many zoos are centers where rare animals are preserved when they are in danger of dying out. These modern zoos also want to give the animals a natural life, so that they are healthy and behave normal. This is done for the animals, but also that people can see the animals as if they were in nature, and not in a zoo.
