Whit Monday Flea Market – L'Isle-Adam

40th Edition 2025 – a landmark event

Whit Monday 2025, 9 June, marked an important milestone for L'Isle-Adam's flea market: the 40th edition organised by the ACIA. The four pedestrian streets of the town centre were transformed into a 2-kilometre market corridor, accommodating around 400 exhibitors. Private sellers, collectors and professional dealers offered an extraordinary range of goods. The atmosphere was exceptional: outdoor concerts, the aroma of spit-roasted pork, and entertainment for all ages confirmed the place of L'Isle-Adam's Whit Monday flea market among Île-de-France's most eagerly anticipated brocante events.
