Historic Sites Act of 1935

The Historic Sites Act became law on August 21, 1935 and has been amended eight times.

This Act establishes, as national policy, the preservation for public use of historic resources by giving the Secretary of the Interior the power to make historic surveys to document, evaluate, acquire, and preserve archeological and historic sites across the country. It led to the creation of – within the National Park Service of the Historic Sites Survey – the Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER).
