Osny Christmas Market

Osny and the Château de Grouchy for Christmas

Osny is a commune in the Cergy-Pontoise urban community, neighboring Pontoise and Cergy in the Val-d'Oise. It is distinguished by one of its most precious heritage treasures: the Château de Grouchy, a historic 18th-century residence surrounded by a vast wooded park. This exceptional setting serves each December as a backdrop for the town's Christmas market, creating a unique atmosphere between historical heritage and festive magic. The château, visible from the park's paths, adds a romantic and magical dimension to the event.

The Parc de Grouchy, a unique setting for the market

The Parc du Château de Grouchy, located on rue William Thornley, is one of the most beautiful sites in Osny and the entire Cergy area. Its century-old paths, majestic trees, and views of the château create an exceptional natural setting, particularly magical in December when the park is illuminated with garlands and lanterns. The Christmas market is set up along the paths and on the lawns of the park, with about thirty wooden chalets offering artisanal creations and gourmet specialties. The juxtaposition of illuminated chalets and majestic trees under the starry December sky creates strikingly beautiful visual scenes.

Thirty quality artisans and producers

The Osny market brings together about thirty creator artisans and local producers whose creations have been selected for their quality and originality. Handmade jewelry, ceramics and pottery, blown glass objects, wood sculptures, papier-mâché creations, original paintings, and illustrations are displayed alongside gourmet stalls offering honey and pollen from local beekeepers, artisanal jams, fine chocolates, gingerbread, and local Val-d'Oise delicacies. These quality exhibitors make the Osny market a showcase for regional craftsmanship and gastronomy.

An exceptional program of activities

The Osny Christmas market stands out for the richness and quality of its entertainment program, designed to delight all ages. The ice rink welcomes beginner and experienced skaters in the illuminated park setting. Creative workshops allow children to make their own Christmas decorations. Face painting sessions transform children into fairies, elves, or wise men. Christmas storytelling sessions are performed by professional storytellers under the park's canopy. Concerts of acoustic music and Christmas carols resonate under the leafy arches. And the sound and light show, projected onto the château's facade, is the highlight of the evening program.

Three festive days

The Osny market takes place over three days, from Friday evening to Sunday afternoon. The Friday evening, from 5 PM to 8 PM, kicks off the festivities in an intimate and nocturnal atmosphere that is highly appreciated. Saturday, from 11 AM to 8 PM, is the main day of the market with the full entertainment program and all chalets open. Sunday, from 10 AM to 6 PM, offers families a last opportunity to enjoy the exceptional park setting and finalize their Christmas shopping in a relaxed and joyful atmosphere.

Osny between history and modernity

The commune of Osny, despite being part of the new town of Cergy-Pontoise, has preserved its historical and heritage character. The Château de Grouchy, the 18th-century town hall, and a few bourgeois residences bear witness to the town's history before the urban development wave of the 1970s. This coexistence of old and new, of the historic town center and the new town, gives Osny a dual identity, both rooted in its past and looking towards the future.
