Happy Bastille Day!
Bastille Day is the celebration of the storming of the Bastille prison by French revolutionaries in 1789. Because the prison represented that which the Revolution was against, it was torn down, brick by brick, by the French people. Its governor, Bernard-René de Launay, was taken prisoner by the mob and killed, becoming one of the first men beheaded for the Revolution.
So, head on down to the Champs-Élysées (or the Upper East side of Manhattan, if that's closer), look at a nice Monet, grab a generous hunk of bread, and wait for the fireworks on the Eiffel Tower in celebration.
