Overview

Fort Knox is a United States Army installation located in north-central Kentucky, approximately 35 miles southwest of Louisville. The facility spans parts of Hardin, Meade, and Bullitt counties, covering about 109,000 acres of rolling terrain. Established in 1918 as Camp Knox during World War I, it served as a training ground for artillery and cavalry units. The installation was named after Henry Knox, the first U.S. Secretary of War and a key figure in the American Revolutionary War.

The post gained permanent status in 1932 and expanded significantly during World War II, becoming one of the Army's largest training centers. Today, Fort Knox serves as the home of the U.S. Army Cadet Command and the U.S. Army Recruiting Command. While best known for the U.S. Bullion Depository that stores much of the nation's gold reserves, the installation primarily functions as a major military training and administrative center. Its strategic location provides easy access to transportation networks while offering sufficient space for large-scale military exercises.
