About Riordan Mansion State Historic Park

Built in 1904 for two Riordan families, Riordan Mansion is an impressive reminder of gracious living in a small, territorial logging town. The historic building is an Arizona treasure — a remarkable example of Arts and Crafts style architecture featuring a rustic exterior of log-slab siding, volcanic stone arches, and hand-split wooden shingles. The expansive home has forty rooms, over 13,000 square-feet of living area, and servants' quarters. The Riordan residence was designed by the creator of Grand Canyon's El Tovar Hotel, Charles Whittlesey.
