The popular festival of the town on the banks of the Seine and its tricolor lanterns
The Herblay Festival brings together the annual festive events organized by the municipality of Herblay-sur-Seine (Val-d'Oise) between June and August: the Fête de la Musique (Music Festival), the National Day on July 13th, and the Summer Village mark the Herblay summer. These major dates are occasionally complemented by open-air concerts, activities in parks, and key community events, in a town deeply attached to its Seine riverbanks.
Herblay, officially renamed Herblay-sur-Seine in 2019, is a town of approximately 28,000 inhabitants whose very name emphasizes its attachment to the Seine. The commune extends over the limestone heights that dominate the river valley at the confluence of the Oise, offering exceptional panoramas. Its Saint-Martin church, perched on the promontory above the river, is one of the town's symbols.
The National Day on July 13th in Herblay-sur-Seine is one of the most anticipated and original events in Val-d'Oise. The evening begins at 9:30 PM with the distribution of lanterns in front of the Salle Simone Veil (43 rue du Général de Gaulle), in the heart of the city center.
At 10 PM, the torchlight procession sets off from the Town Hall park towards the Seine quays. Rue du Val gradually lights up as the procession passes, accompanied by a festive brass band.
At precisely 11 PM, the pyrotechnic and musical show is launched from the left bank of the Seine, visible from the Herblay riverbanks and from the terrace of Saint-Martin church. The reflection of the fireworks on the waters of the Seine, with the Herblay hill as a backdrop, annually creates a strikingly beautiful scene that gathers several thousand spectators.
After the fireworks, an open-air dance party in the Town Hall park, animated by a DJ, extends the festivities late into the night.
The Fête de la Musique on June 21st is celebrated in Herblay-sur-Seine from 7 PM to 11:30 PM with a diverse musical program spread across several locations in the city center and along the Seine riverbanks. Music fills the streets and squares for a festive and free evening that brings together residents and visitors.
Multiple locations are utilized: Place de la Libération (musical opening with the Orphéon d'Herblay and the Conservatoire), Place de la Halle (open stages for Pop Rock, Jazz, Folk, Blues, followed by Hip Hop and Electro Funk DJ sets), Place des Étaux (Indian dance, Electro DJ Set), Rue du Général de Gaulle (Portuguese rhythms, Electro Pop DJ Set), Town Hall park (local Soul, Blues, Country, Pop Rock bands), Rue de Paris (karaoke), and the Maison du Passeur on the banks of the Seine (lounge atmosphere, Electro DJ set). Bars, restaurants, and shops in the city center participate by animating their terraces.
Towards the end of August, the Summer Village takes over Place Alain Casset (André Malraux space): a free event, open to all, with food, a refreshment stand, workshops (first aid initiation, road safety prevention), pétanque, and friendly activities. It's the essential summer event that closes the season before the new school year.
Throughout the summer, Herblay-sur-Seine occasionally offers activities that take over public spaces: open-air concerts, cinema screenings, sports tournaments, children's workshops in parks and on the riverbanks. The developed promenade along the Seine riverbanks is particularly lively during the summer period.
Please note: the Village d'Antan (reconstruction of a village of yesteryear with artisans in period costumes) takes place in September as part of the European Heritage Days — outside the summer period, it goes beyond the strict scope of the Herblay Festival.
Herblay Festival 2026 continues its major summer events: Music Festival on June 21st (7 PM-11:30 PM, multiple locations in the city center and along the Seine), National Holiday on July 13th with lantern distribution, torchlight procession and fireworks over the Seine at 11 PM, followed by the Summer Village at Place Alain Casset at the end of August. Free entry to all municipal activities.
Herblay Festival 2026 revives its most popular festive traditions, with nearly three months of municipal activities. Three highlights punctuate the summer, open to all and entirely free.
From 7 PM to 11:30 PM, music takes over the city center and the banks of the Seine. Several simultaneous stages offer an eclectic program (Pop Rock, Jazz, Folk, Blues, Hip Hop, Electro, Indian dance, Portuguese rhythms, local Soul/Country bands) before DJ sets late in the evening. Shops and restaurants participate by enlivening their terraces.
