The Copper King Mansion in Butte, Montana, is a 34-room Victorian mansion built in 1884 by William Andrews Clark, one of the 'Copper Kings' who controlled Montana's lucrative copper mining industry. Clark became one of the richest men in America and served as a U.S. Senator (though his seat was tainted by bribery allegations). The mansion, now a bed and breakfast, is said to be haunted by Clark himself. Guests have reported seeing the apparition of a distinguished man in Victorian formal wear in the library and on the grand staircase. The ghost is described as proprietary — he seems to be inspecting the house, pausing to look at furnishings and adjusting picture frames. Staff have found artwork straightened overnight and books rearranged on shelves. Other phenomena include the sound of a piano playing in the music room when no one is present, the scent of pipe tobacco in Clark's former office, and footsteps on the third floor when no guests are staying there. The mansion's ornate interior — with hand-painted ceilings, stained glass windows, and imported European furnishings — has been meticulously preserved, creating an environment where the 19th century feels immediate rather than distant.
