A product of the city’s dynamic development in the late 19th century, Wrocław’s zoo dates back to 1865 and became the oldest in the country when Poland inherited it after World War II. Suffering severe wartime damage, many of the zoo’s elegant historic buildings were reconstructed and can be found in the southern part of the park; also don't miss the splendid commie-era neon sign at the entrance. A relatively new addition to the zoo is the impressive African aquarium complex, or 'Afrykarium': several levels of exhibits focused on the diverse aquatic habitats of Africa, with animals including hippos, sharks, manatees, crocodiles, penguins (in Africa? Who knew?), and more. Boasting over 12,000 critters of some 1,100 different species, the zoo is one of Wrocław’s most visited attractions, and visiting it all takes up an entire day.
