A National Historic Site is a designated area in the United States that has been recognized for its historical significance. These sites can include buildings, structures, or locations that are important for their cultural, architectural, or historical value. They are preserved to educate the public and commemorate events or people that have shaped the nation’s history. Managed by the National Park Service, these sites often offer guided tours, educational programs, and interpretive materials to help visitors understand their importance. Examples of National Historic Sites include the Frederick Douglass National Historic Site and the Martin Luther King Jr. National Historical Park.
