A unique blend of historical elements and details characterize the home of W. A. Clark Jr., built in conjunction with the adjacent carriage house in 1900. H. M. Patterson’s asymmetrical design features a granite coursed ashlar foundation, rusticated base, and corbelled brick banding on the first-floor façade. The unusual arched openings are semicircular with pointed crowns and cushion springers. A projecting oriel and classical pediment adorn second-story openings, while intricate modillions support the cornice. Interior appointments include an oak-trimmed vestibule, dining room, and library, with an intricate terra cotta fireplace mantle, further evidence of the family’s wealth. The elder Senator Clark’s sleazy politics and the darker dealings of the Clark family leave locals aghast even today. William, Jr., who lived in the Butte home until 1905, later achieved embarrassing notoriety for benevolent gestures that were apparently intended to hide an aberrant lifestyle.
