Founded in 1838, the Artis Zoo is still as enchanting as it was nearly two centuries ago. Not only is Artis an oasis of peace right at the heart of a fast-paced city, but it is also a haven for some 700 animal species and 200 tree varieties, many on the verge of extinction. Artis is also one of the fewest zoos in Europe to have so many listed buildings within its grounds, namely the Large Museum (1855), the unique Library building (1867) and the Aquarium (1882).
