A National Historic Landmark is a historic building, site, structure, object, or district that represents an outstanding aspect of American history and culture. National Historic Landmarks are nationally significant historic places designated by the Secretary of the Interior because they possess exceptional value or quality in illustrating or interpreting the heritage of the United States. Today, fewer than 2,600 historic places bear this national distinction.
The National Historic Landmarks Program is a Federal designation program.
Please see the National Park Service website for more information on the National Historic Landmarks Program.
