The Mining Exchange Building at Pikes Peak and Nevada Avenue opened to the public on Jan. 15, 1902, nearly two years after the groundbreaking. The building was constructed by mining legend and philanthropist Winfield Scott Stratton. It hosted offices and the stock exchange for Cripple Creek and Victor gold mines. During construction, a massive boiler was ceremoniously delivered and installed by St. Johns and Barnes, a Colorado Springs heating and plumbing company.
