Atchison Storage Facility, Kansas

An hour up the Missouri River from Kansas City, south of Atchison, is a former underground limestone mine that was developed into a military storage facility. The 2.7 million square foot space was turned into a cold storage facility during WWII, to house food for the war effort. After the war, the army used it to store machine tools, and the site was known as the Atchison Caves. The Defense Logistics Agency took it over in 1977, naming it the Atchison Storage Facility, to store a wider variety of military items, including parachutes and documents, until it was sold at a public auction in 2013 for $500,000. Though it has changed hands a few times since then, it is now periodically used as a commercial storage facility.
