KNOX, FORT

major U.S. military reservation (110,000 acres [44,510 hectares]) in Meade, Hardin, and Bullitt counties, northern Kentucky, U.S. It lies 30 miles (48 km) southwest of Louisville. Established in 1918 as Camp Knox (named for Major General Henry Knox, first U.S. secretary of war), it became a permanent military post in 1932. For maximum security the U.S. Bullion Depository, a solid square bomb-proof structure with mechanical protective devices, was built there in 1936 to hold the bulk of the nation's gold. During World War II, the gold vault was used as a repository for the original copy of the U.S. Constitution and Declaration of Independence, the Magna Carta, and the original draft of Lincoln's Gettysburg Address. Since 1940 Fort Knox has been the U.S. Army Armor Headquarters with various training schools. Its Patton Museum of Cavalry and Armor displays American Civil War weapons and captured enemy weapons.
