The Copper King Mansion is a 34-room Victorian mansion built from 1884 to 1888 as the Butte residence of William Andrews Clark, one of Montana's three famous "Copper Kings" who helped establish the fledgling Montana territory through their business ventures.

The Copper King Mansion has been owned, operated and occupied by the Cote family for four generations. It is as much their heritage to preserve now as it was for the Clark family a century before. Recognizing the historical value of the mansion, the Cote family has endeavored to keep the home as close to its original state as possible. Solely funded by tours, bed and breakfast guests, and catered events, the Copper King Mansion remains the only privately owned mansion in Montana accessible to the public.
