Dining room in the ornate Copper King Mansion, now (as of 2022) a bed-and-breakfast inn, in Butte, Montana, a thriving late 1800s and early 1900s gold, silver, and copper mining boomtown — so prosperous that it was known as "The Richest Hill on Earth." The Romanesque Revival-style manor home was completed in 1888 as the residence of William Andrews Clark, who was indeed a "copper king" of the period. Photo by Carol Highsmith, 2022.
