Basel's large zoo is affectionately known as the Zolli by locals. Founded in 1874 with 510 European animals, today the zoo is known more for exotic species.

 With predators, primates, mammals, reptiles, birds, and aquatic life, the population ranges from seahorses to elephants, the latter now enjoying a new elephant enclosure added in 2015 with wallowing pools, showers, and a savannah-like environment. 

The lion enclosure and monkey house are highlights, along with the penguins in the vivarium, which also houses fish and reptiles.
