National Historic Landmark (NHL) status was granted to Fort Ancient State Memorial in 1964. NHL status indicates that a historic or prehistoric site possesses exceptional value as commemorating or illustrating the history of the United States. NHL was formed under the Historic Sites Act in 1935. Harold Ickes, Secretary of the Interior, was seeking a broad legal foundation for a national program of preservation and rehabilitation of historic sites, and wanted a program that would work through the National Park Service to make a survey of historical and archaeological sites, buildings and objects. NHL status works to promote the advancement of historic preservation, patriotic instruction, and tourism promotion. To visit Fort Ancient’s NHL webpage, click here.
