Circa 1884. This turn-of-the-century marvel was built, as the name indicates, by W.A. Clark, one of the nation's leading copper barons. In the early 1900s, Clark made millions each month hauling copper out of Butte's vast mines. Stained-glass windows, gold leafing on the ceilings and elaborate woodwork are just a few of the opulent touches. Clark commissioned artisans brought in from Germany to carve the intricate staircase, which graces the front hall. The mansion is decked floor to ceiling in antiques collected by the innkeeper's mother and grandmother, who purchased the home from Clark's relatives. A three-room master suite includes two fireplaces, a lavish bedroom, a sitting room and a huge bathroom with a clawfoot tub.
