In the late 1800s, the Gilded Age was in full swing, and Colorado was one of the gems of the nation. Beginning with the Pikes Peak Gold Rush, the state’s mines had produced vast fortunes in metals, minerals, and gemstones. Denver became a center of American high society, and mining magnates went from a few lucky claim-stakers to the nation’s nouveau riche. They were millionaires with riches to rival Rockefeller back east, and they were eager to show it off.
The result was the Colorado Mineral Palace—a grand building a short walk north of downtown Pueblo, designed to show off Colorado’s mineral wealth as ostentatiously as possible.
Swedish immigrant Otto Bulow designed the palace in a style inspired by the ancient Egyptians, with huge columns, towering statues, and twenty-one domes, the highest being over 70 feet above the floor of the main hall. The decor in the building was constructed from materials mined or quarried in Colorado, from the sandstone of the columns to the gold leaf and encrusted rubies lining the domes.
