About National Register Listings
The National Register of Historic Places is the official list of the Nation’s historic places worthy of preservation. Authorized by the National Historic Preservation Act of 1966, the National Park Service’s National Register of Historic Places is part of a national program to coordinate and support public and private efforts to identify, evaluate, and protect America’s historic and archeological resources.
Arizona has a strong Native American presence: Arizona is home to 22 federally recognized Native American tribes, including the Navajo Nation, the largest Native American reservation in the country. Native American culture and traditions continue to play an important role in the state's history and identity.
