Rock City Has the Underground Advantage
Over a century after miners in Valmeyer, Illinois milled 6 million square feet of limestone out of a bluff, Admiral Parkway, Inc. developed the cavernous space left behind into a massive underground industrial park called Rock City. With mild temperatures, controlled humidity levels, minimal building material requirements, and natural fire and weather protection, Rock City offers the ideal solution for businesses seeking secure, affordable storage space with easy access to nationwide transportation.
Rock City is located minutes from road, rail, air and water. Custom build to suit your needs. Present occupants include National Archives and Records Administration, Blue Line Foodservice Distribution, Inc., Branding Iron Holdings, Inc., Cargill Meat Solutions Corporation, and Sun Basket,
Inc.
