Wilhelma, built as a royal palace, is now a zoo in Stuttgart, Germany. It is Europe's only large combined zoological and botanical garden and is home to over 8,000 animals from over 1,000 different species and countless exotic plants from over 5,000 different species. The zoo is famous for keeping all four kinds of great apes, all in families with offspring, as well as for its aquarium featuring animals and plants from all over the world. The botanical gardens are renowned for containing Europe's biggest magnolia grove. It was also the home of the polar bear Wilbär. The Wilhelma was originally a royal palace, in Moorish Revival style. After the second world war, it was gradually converted to its present day use. Besides animals and plants, the Wilhelma is therefore also worth visiting for its architecture. (source of information came from wikipedia). The Wilhelma is the best zoo in Germany. Plan on spending the day there. Children under the age of 6 are free and Adults are 12 euros. You might also want to bring your own lunch and drinks. While the zoo does have a couple of cafes the are expensive in my opinion. If you have ever been to the San Diego Zoo, I would say this zoo is a good rival. Don't forget your camera the architectural buildings are stunning.
