 I speak to a lot of people on the phone and there is often a confusion between the National Historic Landmark and National Register of Historic Places designations. National Historic Landmark program was established in 1935 as part of the Historic Sites Act. It has its own set of regulations. A National Historic Landmark is by definition a property that is significant to our nation as a whole. So the process is a nomination is prepared sometimes under what is called a theme study. Theme studies include racial desegregation and civil rights, architecture, there are myriad theme studies out there under which properties are evaluated. Nomination is prepared, reviewed by the National Parks System Advisory Board and recommended to the Secretary of the Interior. The Secretary of the Interior is the only person who can designate a National Historic Landmark. National Register of Historic Places is a bottoms up program. So anyone can prepare a nomination for any property. The process goes through the State Historic Preservation Office. The State Historic Preservation Office nominates it and submits it to the National Parks Service where there is the keeper of the National Register. The keeper has the authority to list things in the National Register of Historic Places. All properties that are designated National Historic Landmarks are automatically listed in the National Register of Historic Places. Some properties go through the process of National Register listing first and then move on to National Historic Landmarks. So a property may be identified as significant at the national level and listed in the National Register and then is recommended for designation as a National Historic Landmark. 1935 Historic Sites Act, 1966 Historic Preservation Act. Two different programs, two different laws, two different methods.
