The Minnesota Zoo (formerly the Minnesota Zoological Garden), is an AZA-accredited zoo in Apple Valley, Minnesota. It is one of two state-supported zoos in the United States, with the other being the North Carolina Zoo. When it opened on May 22, 1978 it was fairly revolutionary in its exhibit design. The zoo, built in a suburbanizing rural area, had more space to house exhibits and was one of the first zoos to organize its animals by their living environment as opposed to their species. It is also home to a high school, the School of Environmental Studies.
