A diverse and multifaceted cultural and educational enterprise, the National Museum of the American Indian (NMAI) is an active and visible component of the Smithsonian Institution, the world's largest museum complex. The NMAI cares for one of the world's most expansive collections of Native artifacts, including objects, photographs, archives, and media covering the entire Western Hemisphere, from the Arctic Circle to Tierra del Fuego. The National Museum of the American Indian operates three facilities. The museum on the National Mall in Washington, D.C., offers exhibition galleries and spaces for performances, lectures and symposia, research, and education. The George Gustav Heye Center (GGHC) in New York City houses exhibitions, research, educational activities, and performing arts programs. The Cultural Resources Center (CRC) in Suitland, Maryland, houses the museum's collections as well as the conservation, repatriation, and digital imaging programs, and research facilities.
