La Conciergerie

La Conciergerie and Sainte-Chapelle include the remains of the oldest Parisian royal palace – the Palais de la Cité, which was converted into a prison in the 15th Century. The Conciergerie thus already had an unpleasant reputation before it became internationally famous as the “antechamber to the guillotine” during the Reign of Terror, the bloodiest phase of the French Revolution. It housed the Revolutionary Tribunal as well as up to 1,200 male and female prisoners at a time.
