The great popular festival of the last weekend of August centered around the onion in the Sénonais region
Every last weekend of August, Villeneuve-la-Guyard (89340) celebrates the onion of its region with this traditional fair created in 1977. For two days, the town center comes alive with a flea market, a funfair, a local produce market, and an onion peeling contest. A brass band, a show evening, and conviviality make this summer event one of the highlights of the summer in the Sénonais.
Since 1977, every last weekend of August, Villeneuve-la-Guyard (89340) transforms into the onion capital. The Onion Fair, organized by the commune's Culture and Festivals Committee, is one of the most popular rural festivals in the Yonne department: it brings together residents, market gardeners, artisans, and visitors around an emblematic vegetable of the Sénonais agricultural plain.
It's no coincidence that this fair originated in Villeneuve-la-Guyard. The town, nestled in the Seine valley on the border between the Yonne and Seine-et-Marne departments, benefits from particularly fertile alluvial land suitable for market gardening. Farmers in this region have long cultivated vegetables, onions, and cereals on the rich silt deposited by the river, supplying the markets of Sens and surrounding towns. The fair was created to celebrate and promote this local production, bringing together producers and consumers in a spirit of celebration and sharing.
The Onion Fair takes over the heart of Villeneuve-la-Guyard across several emblematic streets and spaces: the Town Hall Square, the Grande Rue, the rue Chauveau, and the avenue des Promenades. The entire town center buzzes with non-stop activity for two days.
Saturday begins at 8:00 AM with the setup of exhibitors along the village streets. At 10:00 AM, the official opening takes place at the Town Hall Square to the sound of the Fanfare de l'Espérance Varennoise, which leads a festive parade through the streets. Speeches by officials and an inaugural cocktail at the Salle des Fêtes mark the grand launch of the event.
During the day, the local produce market hosts local producers and food artisans. Seasonal vegetables, fresh and storage onions, oils, cheeses, jams, wines, and craft beers are displayed on the stalls, offering a gourmet panorama of local agriculture. Visitors can taste and buy directly from producers, in the great tradition of French rural fairs.
In the afternoon, sports and community activities take over: demonstrations and introductory sessions by local clubs, a dog show always popular with the public, exhibitions of painting and patchwork, and the unmissable onion peeling contest, which elicits laughter and tears in a good-natured atmosphere.
On Saturday evening, the Promenades transform into a festive stage with the show evening: a convivial meal featuring steaming onion soup and grilled meats, followed by a two-part show—a musical performance and a ball—that extends the celebration until late at night.
On Sunday, the fair continues with renewed vigor. The flea market and second-hand sale attract bargain hunters from the early hours, while the funfair delights the children. At 2:30 PM, new musical entertainment boosts the atmosphere. The award ceremony for the onion peeling contest takes place at 4:30 PM, before the official closing at 6:00 PM, after enjoying one last plate of fries-merguez or a good onion soup.
In the collective imagination of the Sens region and its surrounding towns, the onion holds a special place. Cultivated for centuries on the light, well-drained soils of the Seine valley and the Sénonais plateaus, it is a benchmark market garden crop in this part of northern Burgundy. The diversity of varieties grown—storage yellow onions, sweet red onions, spring white onions—testifies to the agronomic richness of this terroir.
The Onion Fair of Villeneuve-la-Guyard is thus much more than just a festive event: it is a living reflection of a local agricultural identity, a tribute to the market gardeners who tirelessly cultivate this humble and essential vegetable, and a strong symbol of the bond between the town's inhabitants and their nurturing land. Each edition perpetuates this collective memory and strengthens the sense of belonging to a rich and authentic territory.
The Onion Fair belongs to that enviable category of popular rural festivals that add flavor to summer in France. Without artifice or over-media attention, it brings together several thousand people each year—locals, families, passing tourists—in an atmosphere of sincere conviviality. The volunteers of the Culture and Festivals Committee, committed year-round, ensure impeccable organization, from welcoming exhibitors to the logistics of the show evening. Their dedication is the secret to the longevity of this event which, after nearly fifty years, remains a timeless fixture on the Yonne's festive calendar.
Villeneuve-la-Guyard itself is worth a visit: a town of some 1,700 inhabitants, it is ideally located between Sens (20 km north) and Montereau-Fault-Yonne (15 km west), at the confluence of Burgundian and Île-de-France influences. The parish church, the banks of the Seine, and the surrounding hiking trails nicely complement a visit during the fair.
The 48th Onion Fair of Villeneuve-la-Guyard will take place on August 29 and 30, 2026. Two days of popular festival in the town center: flea market, local produce market, funfair, onion peeling contest, brass band, exhibitions, and sports activities. On Saturday evening, a show and ball at Les Promenades. Free entry for this traditional Sénonais fair created in 1977.
