The story
The Copper King Mansion on West Granite Street in Butte, Montana, was completed in 1888 for William Andrews Clark, one of the three 'Copper Kings' whose fortunes were dug from the richest hill on earth and later a United States senator; its thirty-four rooms of carved woodwork, frescoed ceilings, stained glass and a built-in pipe organ survive remarkably intact, and the house operates today as a bed and breakfast and tour home. Its haunted reputation has grown with the tours: guides and overnight guests have described footsteps on the grand staircase, stray notes from the organ, doors unlatching, cold spots in the third-floor ballroom, and occasional figures in Victorian dress, gently attributed in local telling to members of the Clark household or their staff. The stories are affectionate rather than dark, fitting a house that is more monument than mystery. These accounts should be presented as guest and guide reports and local folklore rather than proven phenomena. Current tour and room details should be confirmed from the official site before publishing.
