Tour SubTropolis: The World’s Largest Underground Business Complex.®

What is SubTropolis? SubTropolis was created through the mining of a 270-million-year-old limestone deposit. In the mining process, limestone is removed by the room and pillar method, leaving 25-foot square pillars that are on 65-foot centers and 40 feet apart.

The pillars’ even spacing, concrete flooring and 16-foot high, smooth ceilings make build-to-suit facilities time and cost efficient for tenants. A tenant requiring 10,000 to one million square feet can be in their space within 120 days. SubTropolis is completely dry, brightly lit, with miles of wide, paved streets accessed at street level.

SubTropolis is home to Ford’s NAVLOS facility; VAWD accredited and cGMP compliant pharmaceutical operations; currently houses over 1,400,000 SF of government, archival, and record storage tenants; is first-stop/last-stop for FedEx and UPS; and more.

Members will travel by bus to SubTropolis where we will learn more about the development and it’s history before taking a guided bus tour. There is an additional fee to attend the tour.
