The 15th arrondissement of Paris (French: XVe arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, it is referred to as le quinzième ('the fifteenth'). The 15th arrondissement, called Vaugirard, is situated on the left bank of the River Seine. Sharing the Montparnasse district with the 6th and 14th arrondissements, it is the city's most populous arrondissement, with a population of 229,472 as of 2020. Tour Montparnasse – the tallest skyscraper in Paris – and the neighbouring Gare Montparnasse are both located in the 15th arrondissement, at its border with the 14th. It is also home to the high-rise Beaugrenelle district and the Front de Seine riverside development, as well as the Paris Expo Porte de Versailles convention centre, where the 180-metre Tour Triangle is set to house a 120-room hotel and 70,000 square metres (750,000 sq ft) of office space in 2026. Close is the Héliport de Paris, the city heliport, just nearby the border with Issy-les-Moulineaux.
