The world's largest indoor desert, the Desert Dome, located under the world's largest glazed geodesic dome, has become a landmark for the city of Omaha. The Desert Dome features plant and animal life from three deserts around the world: the Namib Desert of southern Africa, the Red Center of Australia and the Sonoran Desert of the southwest United States. The Desert Dome contains 84,000 square feet on two levels (42,000 square feet on each level). Located beneath the Desert Dome exhibit is the Kingdoms of the Night, the world's largest nocturnal exhibit.
