It is built on the location of the former royal palace of Saint Louis, from which the Sainte Chapelle still remains.
It houses various courts:
* the Paris court of large claims;
* the Paris correctional court;
* the Paris Court of Appeal;
* the French Cour de cassation (highest jurisdiction in the French judicial order).
It also houses the Conciergerie, a former prison which is now a museum. The Conciergerie is notable in part because Marie Antoinette was imprisoned there before being executed on the guillotine.
