The 14th arrondissement of Paris, officially named arrondissement de l'Observatoire, is one of the 20 arrondissements of Paris, the capital city of France. It is situated on the left bank of the River Seine, containing most of the Montparnasse district. Although today Montparnasse is best known for its skyscraper, Tour Montparnasse, as well as its major railway terminus, Gare Montparnasse, both are only partially located in the neighbouring 15th arrondissement.
