Osny, a dynamic town in the Val-d'Oise
Osny (95520) is a town in the Val-d'Oise located immediately west of Pontoise, the department's prefecture. With its approximately 17,000 inhabitants, Osny is a residential and commercial town that benefits from its proximity to Pontoise while having its own identity and facilities. The town has a rich associative fabric and green spaces appreciated by families.
The National Day on July 14th is a highlight of Osny's municipal calendar. Each year, the town hall organizes a complete festive program so that all Osny residents can celebrate the French Republic together in a spirit of joy and fraternity.
Fireworks in the heart of the town
The July 14th fireworks display is the culmination of the festivities in Osny. Fired from one of the town's large green spaces or parks, this pyrotechnic show brings together thousands of residents who settle on the lawns to enjoy the spectacle in the best conditions. The summer night, with its mild temperatures, invites a long evening outdoors before and after the fireworks.
The town hall ensures that the fireworks are visible from many points in the municipality, allowing people with reduced mobility or families with very young children to enjoy the show without moving too much. The choice of the firing location is made each year in consultation with municipal services to optimize safety and spectator enjoyment.
Afternoon entertainment
The afternoon of July 14th is enlivened in Osny by a program for the whole family. Inflatable games, sports activities offered by local clubs, and food and entertainment stalls allow residents to gather in a festive atmosphere from the beginning of the day. Osny associations are highlighted during these events, which increases their visibility and their roots in local life.
Children are particularly spoiled during these summer festivities: rides, clown shows or street artists, creative workshops. The Osny town hall pays particular attention to the quality of the entertainment offered to the youngest, as National Day is also an opportunity to pass on attachment to republican values to children.
Torchlight procession and popular ball
The torchlight procession marks the transition from day to night during National Day in Osny. This procession, carrying candles and lanterns, crosses the town's neighborhoods in a solemn and festive atmosphere. It brings together municipal elected officials, associations, and residents for a symbolic parade that recalls revolutionary traditions.
After the fireworks, a popular ball allows residents to continue celebrating the Republic in good spirits. This legacy of French republican tradition is particularly appreciated by residents who find in these outdoor balls a conviviality and simplicity that are precious in the modern world.
