The Bastille column sits on the site of the old Bastille prison which was torn down in 1789 at the beginning of the French Revolution. It actually commemorates another revolution -- the Revolution of 1830 -- when the French, once again, overthrew their king. Today, it remains a site of popular protest when people want to make their voice heard in Paris. But at night, that symbolism gives way to the beautiful illumination of the column against the sky.
Update on a previous post: Ellen showed my photograph of the Angela Davis image in Paris to her class, and one of her students identified it as the work of Obey. See http://obeygiant.com for more information, including other uses of that same image of Davis.
