The vault hoards a great share of the country's gold reserves along with other valuable items belonging to or under the supervision of the federal government. It presently reserves approximately 147 million ounces (4,580 metric tons) of gold bullion, which is more than half of the Treasury's deposited gold.
Other U.S. Bullion Depository locations include the West Point Mint, presently holding 54 million ounces (or 22%) of the country's gold, with mints in Denver, Philadelphia, and San Francisco holding lesser shares. The U.S. Mint Police is responsible for protecting all federal depositories.
In 1988, the Fort was listed on the National Register of Historic Places for its reputation as a renowned landmark that is often mentioned in factual and fictional contexts. It holds great significance in U.S. economic history.
What makes the U.S. Bullion Depository, Fort Knox one of the world's most secure buildings? Read on to find out.

The Depository measures 105 x 121 feet (32 x 37 meters) and is 42 feet (13 meters) above ground level. The cost of construction was a mere $560,000 in the 1930s.
Materials used in construction include:
The external wall is composed of concrete lined with granite. There are four guard boxes at every corner of the construction. At the entry gateway, guard boxes are positioned and over the marble front entrance the words 'United States Depository' are engraved.
Above the inscription is the gold seal of the Department of the Treasury. At the back of the building is another entry used for receiving gold and other provisions.
Under the fort-like building is the gold vault composed of steel plates, steel I-beams, and steel cylinders fastened with hoop bands and enclosed in concrete. The building is two stories high with an area of less than 4,000 square feet (370 square meters).
According to Mosler Safe Company, the vault constructor, both the vault gate and emergency gate are 21 inches (53 centimeters) thick and are made of the latest torch-and-drill-resistant material of the time.
The central vault gate weighs 20 short tons (18 metric tons) and the vault sheath is 25 inches (64 centimeters). The vault gate is set on a 100-hour time lock and is seldom unlocked. To unlock the vault, staff members must enter discrete combinations known only to them.
The lower level of the vault features an escape tunnel leading into the main building for anyone locked in by chance. It can only be unlocked from inside the vault and only when the main vault gates are shut and sealed.
The building is enclosed by railings and is protected by the U.S. Mint Police. Many of these railings are said to be electrified. Each corner of the building features a guard tower operated by several security guards who keep an eye on each region.
Rings of razor wire and minefields are located between the outer boundary and the walls. The premises are scrutinized by high-res night vision cameras and microphones. The depository also boasts its own backup power and water systems. For security purposes, guests are not permitted inside the facility.
Some key items safeguarded in the Depository include:
Fort Knox presently holds 147.3 million ounces of gold. As per the government, the bullion has a book value of $6.22 billion, but that is based on a fixed value set from 1973. Based on the existing gold market value, the assets are worth more than $190 billion.

The gold mostly exists in the form of 27-pound bars, whereas some gold is in the form of coins. Initially, the objective of keeping this stockpile of gold was to offer support for U.S. currency, however, the dollar was taken off the gold standard in 1971.
Apart from gold, the Depository also keeps a reserve of drugs, including morphine sulfate. During the Cold War, the U.S. army wanted to be sure it had an abundant supply of pain medications if external opium sources were lost. Therefore, Fort Knox held plenty of opium in 1955. In 1993, the government expended millions refining the substance into morphine.
During World War II, the gold vault served as a depository for the original copy of the U.S. Constitution, Declaration of Independence, and the original draft of Abraham Lincoln's Gettysburg Address. In 1944, the documents were sent back to Washington, DC.

The vault previously deposited precious objects for other government organizations, such as the Magna Carta, and the crown, sword, scepter, orb, and cape of St. Stephen, King of Hungary before returning them to Hungary in 1978.

'As secure as Fort Knox' is a staple in American slang indicating absolute security of any person, place, or thing. The Depository has gone through many modifications during its 80-year history.
The security of the Depository is well-known for its mysteriousness and legendary mythology. Only a few people know the real structure of the facility and the items safeguarded inside. No one knows all the techniques to unlock the vault.
Enclosed by a series of railings and built with granite walls, the vault is sheltered by a 20-ton blast-proof security gate that requires codes unique to every depository staff member.
The roof is said to be explosion-proof. According to the Treasury, nobody knows the whole combination to open the door, which is resilient to torches, military exercises, and explosives.
The mechanical defenses in the structure include automatic electric-signal systems and telephones, radios, and microphones. The building is also said to be equipped with laser wire and seismographic sensors to guarantee that no one approaches unnoticed.
Although the U.S. Bullion Depository does not possess as much gold as the Federal Reserve Bank of New York, entrance to Fort Knox is more limited.
While everyday excursions operate in the Federal Reserve facility, the Depository has only permitted external guests into the building twice since its completion in 1936: once in 1974 and then in 2017.
The Depository is near the Fort Knox Army post which provides extra security. Fort Knox is protected by the U.S. Mint Police, one of the oldest federal law enforcement organizations.
The officers go through 12 weeks of elementary training followed by an additional five weeks of field training. They learn extensive skills, including how to handle weapons, confronting, door entry, and room clearing.
If that does not appear daunting enough, Fort Knox is located at the center of a 109,000-acre U.S. Army post and is a training site for troops from across the country. There are living apartments for the guards and there is a pistol range for practice underground.
