Boulogne-Billancourt — known locally as simply Boulogne — is the most populous commune in Île-de-France and one of the wealthiest suburbs in France. Its transformation from an industrial town (home of the Renault factory until 1992) into a sophisticated residential and business district is one of the great urban reinventions of modern France. Today it attracts upper-middle-class French families, young professionals, and a growing international community, particularly those working in the La Défense business district or in media and technology companies headquartered in Boulogne.
Boulogne-Billancourt shares a border with the Bois de Boulogne, giving residents direct access to Paris's vast forest park without needing to cross into the 16th arrondissement. The southern entrances to the Bois via Porte de Saint-Cloud and Porte d'Auteuil are within cycling distance of most of Boulogne's residential areas. Roland Garros tennis complex and the Hippodrome de Longchamp racing track are accessible via these gates.
Boulogne is served by metro lines 9 and 10, providing direct access to central Paris. Line 9 connects Boulogne-Billancourt (Marcel Sembat, Billancourt stations) to the Champs-Élysées, Opéra, and République in under 20 minutes. The T2 tram runs north along the Seine riverbank from Issy-les-Moulineaux through Boulogne to La Défense — a useful and scenic route. The RER C is accessible at Boulogne-Pont de Sèvres, connecting to Versailles in 30 minutes and to the city centre.
Boulogne has excellent commercial infrastructure for daily life. The centre-ville around the Rue du Vieux-Pont-de-Sèvres and Avenue Edouard Vaillant offers a mix of French high-street shops, independent boutiques, and specialty food stores. The weekly market at Place Marcel Sembat (Saturday mornings) is a lively, high-quality affair. For larger shopping, the Vélizy 2 and Rosny 2 malls are accessible by car, and the Grand Marché de Boulogne provides a good covered market for daily shopping.
Boulogne-Billancourt's layout — a mix of residential streets, industrial-era boulevards, and riverfront open space — combined with its direct connection to the Bois de Boulogne, gives it marginally better air quality and slightly more breeze than the densely built inner arrondissements. The Seine riverfront provides an open corridor that channels westerly breezes, making the Rives de Seine development area particularly pleasant on warm summer days.
