The National Register of Historic Places (NRHP) 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. Listing on the NRHP provides potential eligibility for State and Federal tax benefits and grants. National Register Districts are different than local historic districts. Unlike properties on local historic registers, listing on the National Register does not have any regulatory implications. Owners of private property listed on the NRHP are free to maintain, alter, manage, or dispose of their property as they choose provided no Federal financial incentives or permits are involved.
