During the cold war, the US Federal reserve needed a place to store enough US currency to replenish the country east of the Mississippi, in case of a nuclear strike. In 1969, a bunker was built into the bedrock of Mount Pony in Culpeper, Virginia to hold billions of dollars in US currency.
It had 7 computers that were tied into the Federal reserve system as well as barbed wire fences, guards and other forms of protection.Inside, the 140,000 foot facility contained 124 concrete vaults, “radiation-hardened” and steel-reinforced, to safeguard thousands of pallets stacked with money (which, oddly, was mostly in two-dollar bills). It also served as a continuity of government facility up until 1992.
In 1997 it was put up for sale and was jointly purchased by the US Library of Congress and the Packard Foundation (of Hewlitt-Packard fame).They had a great idea for what the old bunker could be used for.
Now, the facility contains 1.1 million film, television, and video recordings.
