Est. 1898 · Clark Family Mansion · French Chateau Architecture · Copper Boom Era · Butte Arts and Humanities Museum
Construction on the Clark Chateau began in 1898. Copper magnate and U.S. Senator William A. Clark built the mansion for his eldest son, Charles W. Clark, and the design by architect Will S. Aldrich was modeled on a French chateau the younger Clarks had admired on their honeymoon.
Charles Clark and his wife, Katherine, lived in the house only a few years. By the early 1900s the family had relocated to California, a move that coincided with the legal and political turmoil surrounding the Clark fortune in that era. Katherine Clark died not long after the move, from complications of diabetes. Charles rebuilt his life on the West Coast, and the chateau passed out of family use.
The mansion later took on civic and cultural roles and today operates as the Clark Chateau, a museum that interprets Butte's history through the humanities and hosts rotating art exhibits. Guided tours cover all four floors of the building, and its French-influenced design remains one of the more distinctive surviving mansions of Butte's copper-boom elite.

The chateau's haunting reputation centers on the third floor. People who have visited or written about the building describe sounds and the occasional sighting there, reported at different hours of the day rather than only after dark.
Regional ghost roundups and at least one paranormal group's writeup list the chateau among Butte's reportedly haunted buildings, framing it as a grand mansion said to retain activity from its early decades. The accounts are general, the kind that attach to large, much-altered historic houses, and no single named figure dominates the stories.
The museum's public identity is its architecture and its rotating humanities and art programming rather than the paranormal. The haunted reputation is mentioned on tours and in local coverage but is not the basis on which the chateau presents itself to visitors.
Guided tours of the Clark Chateau cover all four floors and the rotating humanities and art exhibits the museum hosts. The building's haunted reputation, focused on the third floor, comes up on tours but is not the museum's primary focus.

Yuma, AZ
Yuma Territorial Prison operated from 1876 to 1909 on a bluff overlooking the Colorado River in Yuma, Arizona. It held 3,069 prisoners during its 33-year operation, including 29 women. The facility became a state historic park and has been voted by USA Today readers as the Best Haunted Destination in the nation.
Hancock, MI
The Quincy Mining Company began extracting copper from the Keweenaw Peninsula in 1846 and operated continuously until 1945, producing nearly a billion pounds of copper. During that period, 253 workers died in documented underground accidents. At its deepest, the mine reached 9,000 feet — the deepest copper mine in the world at the time — and its No. 2 shaft hoist house is a National Historic Landmark.
Butte, MT
The Dumas operated as a brothel from 1890 to 1982, said to be the longest continuously operating brothel in the United States. It is now a museum of Butte's red-light district.
