The most notable thing about this giant plaza is the building that’s no longer here: the Bastille prison. Now an enormous traffic circle where cars careen around at warp speed, this was once the site of an ancient stone fortress that became a symbol for all that was wrong with the French monarchy. Over the centuries, kings and queens condemned rebellious citizens to stay inside these cold walls, sometimes with good reason, other times on a mere whim. By the time the Revolution started to boil, though, the prison was barely in use; when the angry mobs stormed its walls on July 14, 1789, there were only seven prisoners to set free. Still, the destruction of the Bastille came to be seen as the ultimate revolutionary moment; July 14 is still celebrated as the birth of the Republic. Surprisingly, the giant bronze column in the center honors the victims of a different revolution, that of 1830.
