National Day in Sannois, town of vineyards and windmills of Val-d'Oise
Sannois celebrates National Day every July 14th in this picturesque town in Val-d'Oise, known for its historic windmills and renowned vineyard. The national celebration brings together the people of Sannois for a festive program combining fireworks launched from the windmill hill, a popular ball in the republican tradition, family entertainment, and a torchlight procession. A free and popular celebration in this charming corner of the Argenteuil hillside.
Sannois (95110) is a commune in Val-d'Oise perched on the hillsides between Argenteuil and Enghien-les-Bains. With its approximately 26,000 inhabitants, Sannois is a medium-sized town that benefits from remarkable natural and historical heritage. The town is particularly known for its windmills, several of which have been preserved and restored, and for its municipal vineyard which produces an AOC Île-de-France white wine appreciated by connoisseurs each year.
The windmill hill, overlooking the Argenteuil plain, offers panoramic views of the region and is a popular natural space for walkers. It is from these heights that the July 14th fireworks illuminate the sky above the plain.
The July 14th fireworks in Sannois benefit from an exceptional setting. Launched from the heights of the windmill hill or from the town's green spaces, they are visible from surrounding towns and offer spectators gathered on the lawns a large-scale pyrotechnic show. The view of the Argenteuil plain illuminated by colorful rockets is particularly striking.
The inhabitants of Sannois gather in the green spaces of the hill from the early evening, with picnics and blankets in hand. The atmosphere before the fireworks is that of beautiful summer evenings: lively conversations, children running, the scent of grass and the nearby vineyard.
The municipal vineyard of Sannois is one of the town's most appreciated curiosities. This vineyard, replanted in the 1980s on the former wine-growing hillsides, produces grapes each autumn that are vinified in a cooperative cellar, yielding a light and fruity white wine. The Grape Harvest Festival in October is Sannois's other major festive event, but July 14th, preceding this harvest, already allows visitors to admire the vines in full summer growth.
In some years, activities related to the vineyard may be offered during the July 14th festivities: grape juice tasting for children, exhibition on the wine-growing history of Sannois, walks through the vineyards.
The National Day of Sannois mobilizes many local associations that contribute to the day's entertainment. From the afternoon onwards, sports and cultural activities liven up the town's parks and squares. The torchlight procession winds through the streets of Sannois in a festive and solemn atmosphere. The popular ball, after the fireworks, brings residents together in a friendly and relaxed atmosphere.
The official July 14th ceremony, with the mayor's speech and a wreath-laying at the war memorial, reaffirms Sannois's commitment to republican values and the memory of those who fought for freedom each year.
