National Treasure
Benjamin Franklin, a hidden Freemason cipher, and the Declaration of Independence — the film that made cipher tourism American.

Why This Matters
National Treasure (2004) wove real American history — Freemason architecture, the layout of Washington D.C., the symbolism on the dollar bill — into a cipher-hunt adventure narrative. While no treasure actually exists behind Independence Hall, the film sent millions of viewers to examine the actual historical record of Founding-era cryptography: Benjamin Franklin genuinely used codes in his diplomatic correspondence; George Washington ran the Culper spy ring with invisible ink; and Freemason imagery in early American civic architecture is a documented historical fact, even if not a cipher.
The film uses a book-cipher clue associated with the Declaration of Independence and other invented treasure-hunt devices. These are fiction, not evidence of an actual concealed map or treasure. The Beale pamphlet belongs to the nineteenth century, and an anagram rearranges letters rather than substituting them.
Benjamin Franklin was a Freemason — he joined St. John's Lodge in Philadelphia in 1731. Washington D.C.'s original plan by Pierre Charles L'Enfant does include diagonal avenues cutting through a grid, and some Freemason researchers claim pentagram and compass shapes in the layout, though this is contested. George Washington did operate a sophisticated intelligence network using the Culper Ring (see the exhibit). The Founders corresponded in codes and ciphers, particularly in sensitive diplomatic channels via invisible ink.
The franchise helped popularise the image of historical documents as puzzle clues. It could not have inspired Byron Preiss’s The Secret, which appeared in 1982, more than two decades before the 2004 film. Specific claims about effects on tourism or later puzzle design require their own evidence.
