The Detroit Zoo is located about 2mi north of the Detroit city limits at the intersection of Woodward Avenue, 10 Mile Road, and Interstate 696 in Royal Oak and Huntington Woods, Michigan, United States. The Detroit Zoological Society (DZS), a non-profit organization, operates both the Detroit Zoo and the Belle Isle Nature Center, located in the city of Detroit. The Detroit Zoo is one of Michigan's largest family attractions, hosting more than 1.6 million visitors annually. Situated on 125 acres of naturalistic exhibits, it provides a natural habitat for more than 2,000 animals representing 245 species. The Detroit Zoo was the first zoo in the United States to use barless exhibits extensively.HistoryThe first Detroit Zoo opened in 1883 on Michigan and Trumbull Avenues, across from the then site of Tiger Stadium. A circus had arrived in town, only to go broke financially. Luther Beecher, a leading Detroit citizen and capitalist, financed the purchase of the circus animals and erected a building for their display called the Detroit Zoological Garden. The zoo closed the following year and the building converted into a horse auction.The Detroit Zoological Society was founded in 1911, but the zoo's official opening did not occur until August 1, 1928. At the opening ceremony, acting Mayor John C. Nagel was to speak to the gathered crowd. Arriving late, Nagel parked his car behind the bear dens and as he came rushing around the front, Morris, a polar bear, leaped from his moat and stood directly in front of Nagel. Unaware how precarious his situation was, Nagel stuck out his hand and walked toward the polar bear joking, "He's the reception committee." The keepers rushed the bear and forced him back into the moat, leaving the mayor uninjured.
