The big annual flea market on the Vlasto field, in the Seine loop
Every year in early summer, the Mézy-sur-Seine school fund organizes a large flea market on the Vlasto field. From 8am to 7pm, private and professional exhibitors offer furniture, antiques, crockery, clothing, toys and trinkets to bargain hunters from the Yvelines and the Paris region. On-site refreshments, free admission, in a green setting in the heart of the village.
In the heart of the Seine valley, the annual Mézy-sur-Seine flea market is one of the most anticipated early summer rendezvous for bargain hunters in the department. Organized by the school fund, it takes place on the Vlasto field, a beautiful open-air space that accommodates many exhibitors for a full day of displays. The event starts early in the morning, from 8am, and continues until early evening, around 7pm.
Individuals and dealers share the aisles, offering a very diversified selection: antique furniture, crockery and tableware, trinkets, glassware, vintage textiles, toys, old books, records, costume jewelry, tools, old linen, small appliances.
The profits from the flea market go to the Mézy-sur-Seine school fund, which finances educational projects, school trips and educational materials.
A rural town of around 1,700 inhabitants, Mézy-sur-Seine is part of the Grand Paris Seine et Oise urban community.
