United States Bullion Depository

The United States Bullion Depository, often known as Fort Knox, is a fortified vault building located next to the United States Army post of Fort Knox, Kentucky. It is operated by the United States Department of the Treasury. The vault is used to store a large portion of the United States' gold reserves as well as other precious items belonging to or in custody of the federal government. It currently holds roughly 147 million troy ounces of gold bullion, a little over half the total gold presently held by the federal government. The United States Mint Police protects the depository.
