Flag of the tricolor on their cheeks, a lantern in hand, and a craving to party running in their bones? No doubt, the National Day is fast-approaching! Every July 14, France lights up the sky—literally and figuratively—with its explosive mix of parades, popular dances and fireworks. And this year again, the Val-d’Oise (95) isn’t planning to stay in the Eiffel Tower’s shadow!
HEATWAVE ALERT — In line with the July 9 prefectural order, the fireworks planned for National Day have been canceled. The towns of Méry-sur-Oise and Mériel will still go ahead with the celebration. The park opens at 6:00 p.m. A republican picnic, dancing, and percussion start at 6:30 p.m. A community dance from 8:30 p.m. to 1:00 a.m. To prevent any risk of fire, lantern distribution is also canceled. Alcohol consumption (beer or wine) is permitted only within the park boundaries. Strong spirits are not allowed. The park will be closed to the public that day until 6:00 p.m. for preparations.
The towns of Méry-sur-Oise and Mériel are gearing up to host a festive evening on Monday, July 13, the eve of the public holiday, in the bucolic setting of the park of the Méry-sur-Oise castle. Bring your singing voices, your picnic baskets, and your best dance moves! Each year, the traditional program features a communal dance and a fireworks display. A National Day celebration done to the letter.
Festivities: a family or friends' picnic, with activities for all ages.
Public dance: dance and revel well into the night.
Fireworks: a spectacular sky‑lit finale to cap off the evening.
Convivial atmosphere: a republican celebration filled with joy and good spirits. On-site dining: beverage stands and food stalls to keep attendees fed throughout the evening.
In short, a July 13th made in Méry-Mériel that is shaping up to be festive and convivial.
