William A. Clark Mansion

Butte National Historic Landmark District

Self-made multimillionaire William Clark spent an estimated $260,000 on the construction of this splendid thirty-two-room residence between 1884 and 1888. Though an astounding sum, that figure represented only a half-day’s earnings out of Clark’s seventeen-million-dollar a month income. The irregular architectural plan, a classic of Queen Anne styling, features porticos, arched windows, and elaborate decorative elements. The interior boasts finishing in a different wood for each room, frescoed ceilings, and Tiffany stained glass windows and chandeliers. The intricately carved staircase took four years to complete and was dismantled and displayed at the 1904 Worlds’ Fair in St. Louis.
