National Archives' Charters of Freedom and conspiracy lore

The National Archives' Rotunda houses the original Declaration of Independence, the U.S. Constitution, and the Bill of Rights-collectively called the Charters of Freedom-and displays them under strict conservation conditions including controlled lighting and humidity. A persistent local and national lore claims that the documents on display are facsimiles or have been secretly replaced; the National Archives publicly affirms that the originals are exhibited with conservation measures and limited exposure. The existence of these claims is part of local lore and has been addressed by the Archives as misinformation, while the physical conservation practices are documented.
