The National Park Service manages two programs -- the National Historic Landmarks Program and the National Historic Landmarks Program -- which manage lists of especially important places in the nation's history.
National Register of Historic Places
The National Register of Historic Places (National Register) was authorized by the National Historic Preservation Act of 1966. It is the official list of the Nation's historic places worthy of preservation, and 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. National Register listed properties may be significant at the local, state, or national levels of significance.
National Historic Landmarks
The National Historic Landmarks (NHL) program was established by the Historic Sites Act of 1935. NHLs are designated by the Secretary of the Interior in recognition of their exceptional significance as places that contribute to an understanding of the depth and breadth of the lives and history of the American people. NHLs identified for their exceptional importance in archeology either have already yielded significant knowledge or are demonstrated likely to do so. These properties are significant at the national level of significance. NHLs must demonstrate exceptional integrity based upon a property’s professionally demonstrated intactness of deposits and features to the extent that they can address nationally significant research questions. Sites designated as NHLs are automatically listed in the National Register of Historic Places.
