The Metropolitan Zoological Park and Museum District or ZMD is a cultural tax district in St. Louis City and St. Louis County, Missouri. The district has five subdistricts: the St. Louis Art Museum, St. Louis Zoo, St. Louis Science Center, Missouri History Museum, and Missouri Botanical Garden. Of these, all but the Botanical Gardens are located in or near Forest Park. The district collects property taxes from residents of the City of St. Louis (St. Louis City) and St. Louis County and distributes the funds to each subdistrict. Institutions within the subdistrict are public non-profits. Only the Missouri Botanical Gardens charges an admission fee. The other institutions are free to the public, whether or not they live in St. Louis City or County.
