The 15th arrondissement of Paris is one of the 20 arrondissements (administrative districts) of the capital city of France.
Situated on the Rive Gauche (left bank) of the River Seine and sharing the Montparnasse district with the 6th and 14th arrondissements, it is the city's most populous arrondissement. The 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 Parc des Expositions which is near the Parc des Princes and houses Porte de Versailles exhibition centre, the high-rise district of the Front de Seine (or Beaugrenelle). Beside the Seine, Quartier de Grenelle, Vaugirard, from Pasteur to Brancion, the Parc André-Citroën, Maison de la Culture du Japon and the Musée Pasteur.
A Paris that is alive and kicking: the biggest and most heavily populated part of the capital is first seen via the quartiers that used to be villages, like Vaugirard and Grenelle, and where there are still a few workers' cottages and shops. There are Haussman buildings mixed with modern structures and not just in the highly renovated areas such as those beside the Seine and the railway lines of Gare Montparnasse.
