Fireworks barge catches fire during Swiss National Day celebration on Lake Geneva, no injuries reported

A chaotic end to the festivities

On the evening of August 1, 2026, the Swiss National Day fireworks in Saint-Prex, a commune on the shores of Lake Geneva in the canton of Vaud, were abruptly halted when the barge serving as the launch platform caught fire. Spectators who had gathered for the traditional display instead witnessed flames and a series of uncontrolled explosions. The show was stopped before the final bouquet, and the remaining pyrotechnics continued to detonate from the burning vessel. Video footage published by the Swiss media outlet 20 minutes and distributed by the news agency Keystone-ATS showed the structure ablaze on the lake, with the sound of ongoing detonations clearly audible. Witnesses cited by the media confirmed that the display was cut short, depriving the audience of the planned finale. The barge, which was the main vessel for the pyrotechnic display, became engulfed in flames mid-show, forcing organizers to halt the ignition for safety reasons. Despite the interruption, individual fireworks continued to shoot off uncontrollably from the stricken vessel, creating what one report described as a spontaneous and anarchic salvo of rockets.

A rare display under a fireworks ban

The incident took place against the backdrop of a near-total ban on fireworks across Switzerland. Due to persistent drought and a very high risk of forest fires, the canton of Vaud, like most other cantons, had prohibited outdoor fires and the sale and use of fireworks for the National Day celebrations. The only exception was for fireworks launched from a body of water, which allowed the Saint-Prex event to go ahead. The barge was positioned on Lake Geneva, complying with the exemption. Many other communities had cancelled their displays entirely, making the Saint-Prex fireworks one of the few to take place this year. The ban reflected concerns over tinder-dry conditions that had heightened fire danger throughout the region, with authorities warning of the risks posed by any open flame. The Vaud government had specifically authorized water-based displays, deeming them safer than land-based fireworks under the dry conditions.

No injuries, cause under investigation

As of Sunday morning, no injuries had been reported, according to official sources. The exact cause of the fire on the barge remains unknown, and authorities have not yet provided detailed information. The incident did not result in any harm to spectators or crew, and the uncontrolled explosions from the damaged vessel did not cause additional damage. The event, a staple of local National Day festivities, ended prematurely but without casualties. The Vaud cantonal police and fire services have not issued a statement on the cause, and it is unclear whether an investigation will be launched.
