Pierre Grenier Antiques Fair — Boulogne-Billancourt

Pierre Grenier Antiques Fair — A landmark event in Boulogne-Billancourt

For over three decades, the Pierre Grenier Antiques Fair has established itself as one of the most eagerly awaited events in Boulogne-Billancourt. Organised by BB TOYS under the leadership of Agnès Blesle, this annual event takes place on the last Sunday of May along avenue Pierre Grenier and its neighbouring streets — rue de Seine, rue Émile-Duclaux and boulevard de la République — offering bargain hunters several kilometres of open-air antiques and bric-a-brac stalls.

The 2026 edition marks the 36th anniversary of the fair, testament to its enduring popularity. Between 250 and 500 exhibitors — local residents clearing out their attics and professional antique dealers — set up along the pavements and roadways to present an extraordinarily varied array of treasures, curiosities and objects of all kinds. Admission is free for visitors, while stand rental costs €13/m for Boulogne residents and €17/m for external exhibitors.
