In 1904 brothers Timothy and Michael Riordan worked with Charles Whittlesey, the architect who designed El Tovar on the south rim of Grand Canyon, to build this magnificent 13,000 sq. The children of Tim and Michael Riordan deeded the house, garage, original furniture, clothing, and household items, and acreage to the Arizona State Parks system in the 1970s to preserve and protect this pristine ex
ample of early Arizona history and to serve as an educational center for all ages. The park offers information on the history of Northern Arizona through guided tours, hands-on exhibits, lecture series, and educational outreach. Riordan Mansion State Historic Park is owned and operated by Arizona State Parks & Trails. The Riordan Action Network gladly provides support to the park for maintenance, preservation and educational programming. Your donation to the Riordan Action Network is critical. We need your donation to keep Riordan Mansion maintained and open to the public, so that future generations can enjoy this extraordinary example of architecture and learn about this pivotal time in Flagstaff’s history.
