Question: where did the gold at fort knox come from

title: United States Bullion Depository
text: In 1933 , U.S. President Franklin D. 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 .
