the royal family, while the ground floor was used by the courtiers and servants of the court. The chapel suffered major damage during the French Revolution. Afterwards, it was turned into a storehouse of documents for the neighbouring Ministry of Justice. Quai des Orfèvres The Quai des Orfèvres, "The Quay of the Goldmsiths and Silversmiths", is on the southwestern side of the island, alongside the Palace of Justice and the Place Dauphine. In its earlier days, a poultry market was held here; as a result policemen were referred to by the slang term "poulets" or "chickens". Its current name dates from the 17th and 18th centuries, when many celebrated Paris jewellers had their shops here; including Boehmer and Bassenge - who made a famous necklace for Marie-Antoinette - and Georg Friedrich Strass, who invented both the rhinestone and the synthetic diamond. The jewellers' shops have since disappeared, but the street is notable for the imposing office building at 36 Quai de Orfèvres. Constructed between 1875 et 1880 by architects Émile Jacques Gilbert and Arthur-Stanislas Diet, it replaced an earlier building of the President of the Court of Appeals of Paris, which was destroyed by the Paris Commune in 1871. As the home of the Direction régionale de la police judiciaire de la préfecture de police de Paris (Directorate of the Judicial Police of the Paris Prefecture), its address featured in the titles of several very popular French films and detective novels. The fictional detective Inspector Jules Maigret, created by Georges Simenon, had his office here. The police moved out, to the rue Bastion in the 17th Arrondissement, in 2017. The Rue de Harlay and the Cour de Cassation of the Palais de Justice Rue de Harlay runs across the island on the northwest side, separating the Palais de Justice from the Place Dauphine. It is named for Achille de Harlay, the first president of the Parliament of Paris in the early 17th century; his house stood in that location until it was demolished for the enlargement of the Palace of Justice. The building of the Cour de Cassation, a kind of French Supreme Court, looks over the Place Dauphine. Its highly theatrical facade was designed by Joseph-Louis Duc, whose other famous Paris work is the July Column in the Place de la Bastille. It features marble classical columns, pediments and bas-reliefs; there are sculpted lions on the grand stairways, eagles
