This bombproof, fireproof facility protects the nation's most treasured documents. The methods used for storing the documents safely are nearly as interesting as the documents themselves. Sealed glass vaults are raised into the exhibition areas for viewing each day but sink back into safety each night. Among the other documents and artifacts housed here are copies of the Magna Carta and the Emancipation Proclamation, and the rifle used to assassinate John F. Kennedy.
Admission is free.
