This is a very large and wonderful zoo. We can take a cable car around. It is a great place to see the animals in their natural state! The zoo was opened to the public on September 28, 1931. The zoo is called one of the 7 best zoos in the world. The zoo was inaugurated at the wedding of the Austrian Princess and the Belgian Prince. Visitors can see polar bears, Prague orangutans and Sumatran tigers, which is a mixture of fear and excitement.
