Montana Historical Society

Big Sky. Big Land. Big History.

Welcome to the Montana State Historic Preservation Office (SHPO) Website! SHPO works together with all Montanans to promote the preservation of our state's historic and cultural places. From 10,000-year-old archaeological sites to 100-year-old homestead farms, a lot of history has unfolded beneath the big Montana sky. We encourage people across the state to identify, document, recognize and protect the heritage sites of Montana, preserving our rich cultural landscape for generations to come.
