What is a National Historic Landmark, and why was Jefferson National Expansion Memorial designated as one?
In addition to caring for our nation’s parks and historic sites, the National Park Service also administers a variety of programs that identify and protect other significant parts of our nation’s natural and historical heritage. The designation of National Historic Landmark is awarded only to places with national significance. National Historic Landmarks exemplify the very best in our nation’s history and culture, and the enduring values and ideals that came out of important national events. Jefferson National Expansion Memorial, including the Gateway Arch structure and the surrounding landscape, were designated a National Historic Landmark in 1987. The National Park Service is charged by law with protecting National Historic Landmarks within our care.
