The Kings of France lived here, including Louis IX, who had the Sainte-Chapelle built, and Philippe le Bel, who built the Conciergerie. Later used as the Parliament, the building took the name of the Palais de Justice at the time of the Revolution. The building one visits today, much remodelled, has little in common with that ancient palace. The salle des Pas perdus corresponds to the Great Gothic Hall Philippe le Bel, and the first civil court occupies the apartment of Saint Louis.
