Riordan Mansion State Historic Park is open under an agreement with the Arizona Historical Society. This is because the Arizona State Legislature has swept the funds of Arizona State Parks. Funding comes entirely from fees charged at the Park and donations, and funds raised by the Riordan Action Network. For more information or to help, please email RiordanActionNet@aol.com

How to Donate:
