The free zoo was built in 1868. The zoo is divided into two parts, one is the Puri Azee C family Pritzker Family Children39 (39; s Zoo); the other is the Zoo Farm (Farm-in-the-Zoo), where pigs, cows, horses and other animals can be seen on this small farm, and the children can also directly feed these animals here. At the end of the park is the Chicago Museum of History.
