National Historic Landmarks (NHLs) are sites in the United States recognized for their exceptional historical significance. These landmarks can include buildings, structures, districts, or objects that represent important aspects of American history and culture. The designation is managed by the National Park Service, which aims to preserve and promote these sites for public education and enjoyment. To qualify as an NHL, a site must meet specific criteria, demonstrating its national importance. Examples of NHLs include the Statue of Liberty, Independence Hall, and the Golden Gate Bridge. These landmarks help tell the story of the nation’s heritage and contribute to the understanding of its past.
