U.S. Landmarks Timeline
Find out when some of the most historical sites in the U.S. became national landmarks.
The U.S. began the National Historic Landmark Program to recognize and preserve the country's cultural heritage. Although efforts began as far back as the 1930s, when Congress passed the Historic Sites Act, the program became official when a list of designated landmarks was published in 1960.
A National Historic Landmark is defined and recognized by the U.S. government as a building, structure, object, or district that has national historic significance. The U.S. government has designated 2,532 National Historic Landmarks as of 2014. States and cities designate landmarks as well.
