Riordan Mansion State Historic Park

The house was built in 1904 for two Riordan families. 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 Riordan residence was designed by the creator of Grand Canyon's El Tovar Hotel, Charles Whittlesey.
