Mission Statement

The SHPO works in partnership with the federal, state and local governments, Indian Tribes, and private organizations and individuals to assist in planning for the continued use and preservation of heritage resources for the benefit of future Arizonans. In order to fulfill our mission, the SHPO supports educational and outreach activities that bring awareness to Arizona’s rich archeological heritage and unique built environment resources, provides professional guidance on best practices for preservation and conservation, and manages programs to incentivize preservation activities in the private sector.

What is Historic Preservation?

Historic Preservation is the identification, management, and protection of tangible elements from the past for future generations. It is the history that we can see and experience. As we move into the future with the explosion of new technologies, historic preservation provides an anchor to our past.

Historic preservation encourages the protection of historic and archeological resources that are associated with important past events, themes, and people; that are representative of periods and types of architecture; possess high artistic value; or that are likely to yield valuable information about the past. Historic preservation helps us to know who we are by teaching us about from where we came.
