SubTropolis is a 55,000,000-square-foot artificial cave in the bluffs above the Missouri River in Kansas City, Missouri that is claimed to be the world's largest underground storage facility. Developed by late Kansas City Chiefs owner Lamar Hunt via Hunt Midwest Real Estate Development, Inc., it has trademarked the phrase World's Largest Underground Business Complex. Dug into the Bethany Falls limestone mine, SubTropolis is, in places, 160 feet beneath the surface. It has a grid of 16 feet high by 40 feet wide tunnels separated by 25 feet square limestone pillars created by the room and pillar method of hard rock mining. The complex contains almost 7 miles of illuminated, paved roads and several miles of railroad track. |
