Where is the Constitution?

The National Constitution Center owns a rare, original copy of the first public printing of the Constitution. The Constitutional Convention was conducted under an oath of secrecy, so this printing represents the first time that “We the People” saw the Constitution. The original signed, handwritten Constitution is at the National Archives in Washington, D.C.
