Our history was made by the people of the past; it belongs to the people of the future. It is our responsibility to ensure that our actions here in the present build the bridge to link the two.

The Idaho State Historic Preservation Office (SHPO) was established in 1971 as a result of the passage of the National Historic Preservation Act (NHPA) of 1966.  The NHPA was passed to help ensure the stewardship of our irreplaceable heritage which is vital to maintain and enrich our cultural, historical and educational experiences for ourselves and future generations.

Like other states, the Idaho SHPO is supported by a grant through the National Park Service.  SHPO programs focus on seven major areas, as outlined in the National Historic Preservation Act:


The Section 106 Review process provides a local voice for history in federal project planning. In meeting all of these responsibilities, the SHPO works closely with federal and state agencies, local governments, tribal governments, citizen groups, and property owners.

Program staff consists of professionals from the fields of archaeology, architectural history, history, and historic preservation.
