Simon Architectural style Classical Revival NRHP reference # 88000056 Added to NRHP February 18, 1988 The United States Bullion Depository, often known as Fort Knox, is a fortified vault building located adjacent to the United States Army post of Fort Knox, Kentucky. The vault is used to store a large portion of United States official gold reserves and occasionally other precious items belonging or entrusted to the federal government. It is estimated to hold roughly 2.3 % of all the gold ever refined throughout human history.

Roosevelt issued Executive Order 6102, which outlawed the private ownership of gold coins, gold bullion, and gold certificates by American citizens, forcing them to sell these to the Federal Reserve. As a result, the value of the gold held by the Federal Reserve increased from $4 billion to $12 billion between 1933 and 1937. This left the federal government with a large gold reserve and no place to store it. In 1936, the U.S. Treasury Department began construction of the United States Bullion Depository at Fort Knox, Kentucky, on land transferred from the military. The Gold Vault was completed in December 1936 for US $560,000. The site is located on what is now Bullion Boulevard at the intersection of Gold Vault Road. The building was listed on the National Register of Historic Places in 1988, in recognition of its significance in the economic history of the United States and its status as a well - known landmark. It is constructed of granite quarried at the North Carolina Granite Corporation Quarry Complex. The first gold shipments were made from January to July 1937. The majority of the United States ' gold reserves were gradually shipped to the site, including old bullion and newly made bars made from melted gold coins. Some intact coins were stored. The transfer used a special 9 car train manned by machine gunners and transferred to US Army trucks protected by a US Cavalry brigade. In 1974, a Washington attorney named Peter David Beter circulated a theory that the gold in the Depository had been secretly removed by elites, and that the vaults were empty. A group of reporters was allowed inside in order to refute the theory, which had gained traction thanks to coverage in tabloid newspapers and on the radio. Other than this 1974 event, no member of the public has been allowed inside. During World War II, the depository held the original U.S. Declaration of Independence and U.S. Constitution. It held the reserves of European countries and key documents from Western history. For example, it held the Crown of St. Stephen, part of the Hungarian crown jewels, given to American soldiers to prevent them from falling into Soviet hands. The repository held one of four copies ( exemplifications ) of Magna Carta, which had been sent for display at the 1939 New York World 's Fair, and when war broke out, was kept in the US for the duration. During World War II and into the Cold War, until the invention of different types of synthetic painkillers, a supply of processed morphine and opium was kept in the Depository as a hedge against the US being isolated from the sources of raw opium. Construction and security Below the fortress - like structure lies the gold vault lined with granite walls and protected by a blast - proof door weighing 20 tons. Members of the Depository staff must dial separate combinations known only to them. Beyond the main vault door, smaller compartments provide further protection. According to a Mosler Safe Company brochure : The most famous, if not the largest, vault door order came from the Federal government in 1935 for the newly constructed gold depository at Fort Knox, Kentucky. Both the vault door and emergency door were 21 - inches thick and made of the latest torch - and drill - resistant material. The main vault door weighed 20 tons and the vault casing was 25 - inches thick. The facility is ringed with fences and is guarded by the United States Mint Police. The Depository is near the main entrance to Fort Knox, potentially allowing the Army to provide additional protection. The Depository is protected by layers of physical security, alarms, video cameras, microphones, mine fields, barbed razor wire, electric fences, and heavily armed guards. There is an escape tunnel from the lower level of the vault to be used by someone who has been accidentally locked in. For security reasons, no visitors are allowed inside the depository grounds. This policy has been enforced ever since the vault opened, with only two exceptions. The first was an inspection by members of the United States Congress and the news media on September 23, 1974 led by then Director of the United States Mint, Mary Brooks. The second was a similar inspection made by Kentucky Congressmen on August 21, 2017, led by Secretary of the Treasury Steven Mnuchin. Gold As of November 2017, Fort Knox holdings are 4,582 metric tons ( 147.3 million oz. troy ), with a market value of over $100 billion. In contrast, the GDP of the United States was $19.4 trillion as of April 2017. Some of the gold in the depository is in the form of monetary gold coins. The 1933 Double Eagle was also a temporary resident after transfer from 7 World Trade Center in July 2001, until its sale in July 2002 for $7.59 million. Sometime in 2004, ten additional allegedly stolen 1933 Double Eagles were transported to Fort Knox for safekeeping. Not all the gold bars held in the depository are of exactly the same composition. The mint gold bars are nearly pure gold. Bars made from melted gold coins, called `` coin bars '', are the same composition as the original coins, which is 90 % gold. Unlike many. 999 fine gold bullion coins minted in modern times for holding today, the coin alloy for pre-1933 US coins, which were intended for circulation, was a tougher and wear - resistant. 900 fine alloy ( balance copper ) used for all US gold coins since 1837. ( See crown gold for further gold coin alloy history. ) The US holds more gold than any other country, with about 8,133 metric tons in total ( not just at Fort Knox ), or about 2.4 times that of the next leading country, Germany ( which in 2014 owned 3,387.1 metric tons ). Popular culture Samsung Knox, an enterprise mobile security solution developed by Samsung Group is named after Fort Knox. The Depository figures prominently as the focus of the villain 's plot in the 1964 James Bond film Goldfinger. Auric Goldfinger 's goal is to break into the Depository and plant an atomic device. When it explodes, the entire US gold supply will be irradiated for decades to come and the worth of Goldfinger 's own personal gold supply will skyrocket, making Goldfinger richer. The depository is also featured in the finale of the 1952 Bugs Bunny cartoon `` 14 Carrot Rabbit.
