The Declaration Of Independence was signed in Philadelphia in 1776.
The Declaration of Independence of the United States of America, by Armand-Dumaresq, (c. 1873) which has been hanging in the White House since the late 1980s. The date that the Declaration was signed has long been the subject of debate. Within a decade after the event, Thomas Jefferson, Benjamin Franklin, and John Adams all wrote that the Declaration had been signed by Congress on July 4, 1776. This seemed to be confirmed by the signed copy of the Declaration, which is dated July 4.
