National Historic Landmarks Program

National Historic Landmarks (NHLs) are historic places that hold national significance. The Secretary of the Interior designates these places as exceptional because of their abilities to illustrate U.S. heritage. Today, we have almost 2,600 NHLs in the United States. 

The National Historic Landmarks Program uses the skills of National Park Service staff to guide the nomination process for new Landmarks. Working with citizens across the nation, the NHL Program also assists existing Landmarks.
