The Cologne Zoo is one of the oldest and most popular zoos in Germany. More than 10,000 animals call it home, making it one of the most diverse in all of Europe. Its motto is 'Passionate about animals'. One of the main attractions is the Elephant Park, opened in 2004. The spacious Adventure House presents an African river landscape, home to animals like hippos, Nile crocodiles, and Sitatunga antelopes. In 2014, the Clemenshof opened its doors – a lovingly designed replica of a small farmer's courtyard typical for the region, with a petting zoo for children, providing a home for rare local species.
