Having made a fortune from their Arizona Lumber Company, brothers Michael and Timothy Riordan built this sprawling duplex in 1904. The Craftsman-style design was the brainchild of architect Charles Whittlesey, who also designed El Tovar on the South Rim. The exterior features hand-split wooden shingles, log-slab siding and rustic stone. Filled with Edison, Stickley, Tiffany and Steinway furniture, the interior is a shrine to arts and crafts.
Visitors are welcome to walk the grounds and picnic, but entrance to the house is by guided tour only. Tours leave daily and on the hour; advance reservations are accepted.
