Making Tangible the American Experience

National Historic Landmarks (NHLs) are historic properties that illustrate the heritage of the United States. The over 2,600 NHLs found in the U.S. today come in many forms: historic buildings, sites, structures, objects, and districts. Each NHL represents an outstanding aspect of American history and culture. A list of NHLs by state is available here.
