where were the declaration of independence, the constitution, and the bill of rights stored during world war ii?

During World War II, the Declaration of Independence, the Constitution, and the Bill of Rights were carefully stored in vaults at the United States Bullion Depository at Fort Knox, Kentucky, along with the U.S. government's gold reserves for protection. This was done to safeguard these precious documents from potential wartime damage or sabotage. In 1944, as the threat of bombings on the U.S. mainland diminished, the documents were returned to Washington, D.C., to the Library of Congress, where they remained until 1952. After that, they were transferred to the National Archives, where they are permanently housed today in a highly secure vault designed to protect them from fire, shock, theft, and bomb attacks.
