Note: Effective July 1, 2026, and in accordance with House Bill 898, the Idaho State Historic Preservation Office (SHPO) is now part of the Office of Species, Minerals, and Energy Coordination (OSMEC).

As we complete this transition, we do not anticipate impacts to public services. We appreciate your patience and understanding as we finalize administrative and operational updates.

The State Historic Preservation Office (SHPO) encourages the preservation, documentation, and use of cultural resources. Idaho SHPO educates the public about the importance of Idaho’s cultural heritage. Idaho’s historic, archaeological, and cultural resources represent the physical and tangible manifestations of our history; they reflect who we were, where we came from, where we are now, and help shape our outlook for the future. By protecting, preserving, and understanding these important resources, we span the past, the present, and the future, not as separate events or periods, but as an on-going narrative. These resources provide economic, educational, and intrinsic value today and for future generations. The Idaho SHPO works to ensure the state’s historic and archaeological properties are preserved, interpreted, and reused.
