National Historic Landmarks (NHLs) 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, just over 2,500 historic places bear this national distinction. Working with citizens throughout the nation, the National Historic Landmarks Program draws upon the expertise of National Park Service staff who guide the nomination process for new Landmarks and provide assistance to existing Landmarks.
The National Historic Landmarks Program is Moving!
On April 6 and extending through the week of April 10-14, the National Historic Landmarks Program will be moving to the main building of the U.S. Department of the Interior. During this period, please expect limited or interrupted phone service, however, you may reach the program via its information box at firstname.lastname@example.org. We will respond as soon as possible and as move activities allow. Please visit our contact page for our new mailing address as of April 10.
