Île de la Cité
Also known as "Louvre", the arrondissement is situated principally on the right bank of the River Seine. It also includes the west end of the Île de la Cité. The locality is one of the oldest areas in Paris, the Île de la Cité having been the heart of the city of Lutetia, conquered by the Romans in 52 BC, while some parts on the right bank (including Les Halles) date back to the early Middle Ages.
