Here is where Thomas Jefferson wrote the Declaration. The house has been reconstructed and is now part of Independence National Historical Park. The Independence Hall Association, host of these web pages, led the efforts to have the Graff House reconstructed in 1975, in time for the Bicentennial.
People who watched the popular movie "National Treasure" want to know. On the back, at the bottom, upside-down is simply written: "Original Declaration of Independence / dated 4th July 1776." Regarding the message on the back, according to the National Archives, "While no one knows for certain who wrote it, it is known that early in its life, the large parchment document was rolled up for storage. So, it is likely that the notation was added simply as a label." There are no hidden messages.
The Declaration of Independence - US History
On June 11, 1776, the Second Continental Congress appointed a committee of five men to write a Declaration of Independence from British Rule. Those five men were Thomas Jefferson, John Adams, Benjamin Franklin, Robert Livingston, and Roger Sherman. Jefferson wrote the first draft. The committee declared it to be almost perfect. The committee presented the document to the Congress after making a few corrections. Following a few more changes, Thomas Jefferson's work was approved. Church bells rang out on July 4, 1776, the day the Declaration of Independence was adopted and our nation was officially born.
