Fireworks in Élancourt (78): mark your calendar for September 5, 2026.

The intercommunal fireworks display in Élancourt, blocked on Bastille Day 2026 by a prefectural order, awaits you in the skies over Yvelines for this rentrée. The free event takes place along the Coulée Verte on Saturday, September 5, 2026.

Denied its July 14 celebrations, the Élancourt intercommunal fireworks display makes its return this season. Originally scheduled for July 13, it was canceled at the last minute across the Yvelines department (Yvelines (78)), in Élancourt and elsewhere in Saint-Quentin-en-Yvelines, due to the high fire risk. The towns of Élancourt, Maurepas and La Verrière have chosen to postpone it rather than drop it.

Why was the July 13 fireworks display canceled?

The summer of 2026 brought a major heatwave that pushed the Yvelines prefecture to ban all fireworks and festive fires for a short period, via a prefectural order. The measure also covered private individuals, aiming to curb fire risks while keeping firefighters from being overwhelmed during extreme conditions.

In response to the ban, the three organizing municipalities have opted to postpone their jointly staged pyrotechnic show by a few weeks. The event thus shifts from the height of summer to the autumn season, without sacrificing any of its grandeur.

What does this meet-up on the Greenway look like?

Each year, this fireworks display brings together families and neighbors from three towns for a warm, community gathering. The show is launched behind the Commanderie des Templiers and unfolds several minutes of lights visible from the broad lawns of the Coulée verte.

The delay doesn’t dampen the evening’s spirit. Admission remains free, the viewpoint as expansive as ever, and the family-friendly atmosphere locals know well. A nice way to stretch summer a little beyond the height of the season.

Concretely, the Élancourt fireworks display is set for Saturday, September 5, 2026, starting at 9:30 p.m., along the Coulée Verte in Élancourt (78990). As with most outdoor events, it’s best to arrive a bit early to secure a good spot, and bring a picnic if the weather cooperates. For any last-minute updates, the Town updates its information on its official schedule. The mayors of the three towns—Jean-Michel Fourgous (Élancourt), Grégory Garestier (Maurepas), and Nicolas Dainville (La Verrière)—invite us to enjoy this ballet of lights as night falls.
