Gardens to the rear of Palais-Royal
This is where - On July 12, 1789 a young firebrand, Camille Desmoulins, leapt on a café table and announced to the crowd that Necker had been dismissed. "This dismissal," he cried, "is the tocsin of the St. Bartholomew of the patriots !" Drawing two pistols from under his coat, he declared that he would not be taken alive. "Aux armes!" He descended amid the embraces of the crowd, and his cry "To arms!" resounded on all sides. Two days later the Fall of the Bastille occurred. (stolen from wikipedia!)
