State Historic Preservation Office

The State Historic Preservation Office (SHPO) encourages the preservation, documentation, and use of cultural resources. SHPO educates the public about the importance of our cultural heritage so that Idaho’s historic and archaeological properties are preserved, interpreted, and reused for their economic, educational, and intrinsic values and for future generations to appreciate.

On this site you will find information on historic buildings, the archaeology of Idaho State, how to navigate our regulatory processes and how to nominate properties to the National Register of Historic Places. Explore Idaho State’s historic places through our interactive map.
