Brocante of Théméricourt

The Brocante of Théméricourt, a September Rendezvous in the Vexin

Théméricourt (95450) is one of the most remarkable villages in the Vexin Français Regional Natural Park. Its 15th-century château houses both the town hall and the Musée du Vexin Français, making it an exceptional heritage site in Val-d'Oise. Every first Sunday of September, the commune holds its annual flea market, one of the most eagerly awaited events of the Vexin autumn.

The flea market takes place on rue Achim d'Abos, opposite the town hall, in a stunning architectural setting. Up to 100 sellers take their places along this street of limestone houses, 100 metres from the château-mairie. Sellers are welcomed between 5 AM and 7:30 AM, and visitors arrive from early morning. The registration fee is 7 €/linear metre (minimum 2 metres).

The 39th Edition in 2026

In 2026, the flea market celebrates its 39th edition on Sunday 6 September. Since 1987, this event has mobilised the village's volunteers and attracted collectors from across the region. The Théméricourt flea market features both private sellers and professionals, ensuring a diverse offer: antique furniture, tableware, books, collectibles, clothing, tools and objects of all kinds.
