Atchison Storage Facility The Atchison Storage Facility , commonly known as the " Atchison Caves " is a 2 . 7 million square foot underground storage facility in a former pillar limestone mine below the ground in the Missouri River bluffs at Atchison , Kansas . The bunker complex was a secure U . S . government storage facility from World War II until 2013 . In April 2013 it was privatized and sold to a private investor from Springfield , Missouri . The proposed uses of the facility include storage , miscellaneous business uses ( Mo - Kan Underground Business Center and Citadel Caverns ) , an amusement complex ( Extreme Underground ) and a doomsday bunker ( Vivos Survival Shelter and Resort ) . The facility which is adjacent to Jackson Park in Atchison has 125 acres of above ground land and 60 acres of underground storage space and has been called the " World ' s Largest One - Level Storage Facility " History . In 1886 , George W . Kerford began to quarry limestone from the large bluffs 2 miles ( 3 . 2 km ) south of downtown Atchison , Kansas . Initially , the company produced riprap for the Chicago , Burlington and Quincy Railroad , one of several railroads that traveled through the area . The Kerford Quarry Company ' s operations at the site resulted in a series of large caverns supported by pillars of unmined rock . The mines in the quarry grew to encompass more than 60 acreas of underground space . World War II . During the Second World War , the United States War Food Administration was tasked with collecting and storing reserve farm products to support the war effort . A businessman in Atchison suggested to them that the Kerford Mines would be an ideal facility to store perishables due to the constant temperature and humidity in the caverns . In July 1944 , the Kerford Quarry Company stopped their mining operations and began to lease the facility to the government for the sum of US $ 20 , 000 each year . The government immediately began renovations , spending nearly $ 2 million to create a refrigerated storage facility where the temperature would be maintained at 32 degrees . The War Food Administration stored perishables including meat , fruits , vegetables , dairy products and eggs in the facility . By 1949 , reports indicate that the Atchison Storage Facility held nearly 9 , 000 tons of eggs , 20 , 000 tons of prunes , 1 , 000 tons of raisins and nearly 50 tons of milk . The Cold War . In the years leading up to World War II , the Army Ordnance Department suffered from a shortage of the specialized production machine tools . These highly specialized tools were necessary to make the increasingly complex weapons used in modern battles . In the drawdown following the war , the Army began to stockpile these tools to be held in reserve status to be used in the event of another national mobilization . The Atchison Storage Facility , with its constant temperature , low humidity and protection from the building threat of nuclear weapons . was chosen to be part of the Ordnance Corps Production Equipment Readiness Program . The tools were held in a state of readiness , to be shipped nationwide to manufacturers in the event of a national emergency . In 1952 , the facility was renamed the United States Storage Facility - Atchison Caves . The Army converted two of the largest mines ( more than of underground space ) into storage areas with the installation of concrete block walls , concrete floors , electrical lighting , sump pumps , air handling equipment and an extensive dehumidification system . To facilitate moving the large machine tools in and out of the storage facility a truck receiving dock was built near the entrance , a railroad spur and dock were constructed and dock facilities for barges were established on the Missouri River . In addition , a shop to refurbish and maintain the machine tools was established at the facility . At its peak , a private contractor was responsible for maintaining more than 5 , 000 machine tools in the reserve facility . In 1977 , the facility was transferred to the Defense Logistics Agency and it was renamed as the Atchison Storage Facility . It was later used to store surplus parachutes ( more than 8 , 500 ) , medical supplies and important defense department documents , plans and computer files . Documents classified as " Secret " were securely stored inside two large vaults . Until 2013 it was operated by the Army Reserve ' s 88th Regional Support Command in Fort McCoy , Wisconsin . Defense Department documents listed the facility ' s use as storage and training . They list the size of the facility as above ground and below ground . In the 1990s some hazardous materials were identified at a former landfill at the site . Extensive site remediation was conducted and groundwater monitoring is being conducted in cooperation with the State of Kansas . Privitization . In April 2013 the entire facility and property were sold via an online GSA Auction . The final sales price was $ 510 , 001 . 00 . The new owner , Coby Cullins , is a businessman from Springfield , MO . The facility is currently undergoing extensive renovations and will be used as an underground business complex that will house a wide variety of commercial and industrial businesses . Businesses inside the facility include Citadel Caverns , MO - KAN Underground , Vivos , and Extreme Underground . Vivos Survival Shelter and Resort . In the summer of 2013 , the California company Vivos under Robert Vicino agreed to purchase a portion of the facility and is converting it to what it calls " the world ' s largest doomsday shelter " to accommodate " 5 , 000 people living in up to 1 , 500 RVs . Customers will buy a spot and pay $ 1 , 000 per lineal foot of their vehicle . A 25 - foot - long RV would cost $ 25 , 000 plus a $ 1 , 500 charge per person to pay for a year ' s worth of provided food and toiletries . " It is to have indoor golfing , a bowling alley and swimming pool complete with a water slide . There will also be blast doors and an air filtration and ventilation system .
