Tomorrowland Fire: Reconstruction Reveals True Cause

Nearly one year after a devastating fire consumed the main stage of Tomorrowland, an exclusive reconstruction by Belgian newspaper Het Laatste Nieuws has pieced together the sequence of events that led to the blaze. The investigation points to a subcontractor accidentally spraying highly flammable ethanol onto polystyrene foam and wood stage decor during routine testing of fire bowls on July 16, 2025. The fire caused an estimated 30 to 60 million euros in damages, though no injuries were reported.

Context: A Stage Built for Fantasy

The 2025 Tomorrowland edition carried the theme “Orbyz” — a fairytale ice world born from melting glaciers. The main stage was a monumental structure: 160 meters wide, 45 meters high, covering 5,000 square meters of floor space. It featured 323 steel plates, 1,098 tons of scaffolding, 892 square meters of video screens, 1,148 lighting fixtures, 65 fountains, and 2,120 unique decor elements — much of it constructed from highly flammable polystyrene foam and wood. More than 18 months of design work had gone into the centerpiece of the world-famous electronic dance music festival.

The Day of the Fire

On Wednesday, July 16, 2025, in the early evening, roughly 1,000 Tomorrowland staff were working on site at De Schorre recreational domain in Boom, Belgium, preparing for the festival’s opening two days later. A subcontractor — sent by the company that had installed fire bowls for years — was testing the fire bowls on the main stage. These bowls contain built-in spray nozzles designed to spray ethanol to create dramatic high flames during performances.

According to multiple sources close to the investigation cited by HLN, ethanol was accidentally sprayed onto the stage decor during testing. Camera footage reviewed by investigators shows a large section of the stage catching fire almost instantly. “That can only happen if there’s already something flammable on that decor,” one anonymous source told HLN. “Compare it to something drenched in gasoline.”

VRT NWS had previously reported in November 2025 that the fire began during a test with fire bowls, noting that the bowls contained not only fuel but also strontium, a chemical that can act as a fire accelerator by releasing oxygen when heated.

The fire spread with terrifying speed through the polystyrene decor. Stored fireworks began exploding, sending plumes of black smoke into the sky. All workers evacuated safely — remarkably, no injuries were reported. Approximately 100 firefighters responded with 10 pump trucks and 10 tanker trucks, battling the blaze for over two hours. A federal police helicopter was even deployed with a water bucket. The fire briefly threatened nearby vegetation and a residential area but was contained.

A Miraculous Recovery

At an emergency press conference that same evening, spokesperson Debby Wilmsen delivered the news that stunned the music world: “Tomorrowland will continue. It will be without a main stage. But we will do everything to make something beautiful.” Founders Michiel and Manu Beers brainstormed through the night, sketching and calculating. By morning, a plan for a replacement stage was ready. Suppliers were contacted — some just hours after watching their materials go up in flames. Against all odds, the festival opened on July 18 with a new main stage built in under 48 hours.

Who Is Responsible?

The judicial investigation remains ongoing, with the central question being who bears responsibility for the damage. In May 2026, co-founder Michiel Beers stated on the Dutch podcast “De Machine” that the cause was “in all likelihood a poorly connected device that sprayed ethanol… a human error.” He estimated the damage at approximately 30 million euros, though De Morgen reported that VRT NWS sources had previously put the figure closer to 60 million.

More than 30 parties are involved in the legal proceedings, which include both a criminal investigation for unintentional arson and civil liability proceedings. The identity of the subcontractor who conducted the fire bowl testing has not been publicly revealed.

Safety Report: Could It Have Been Worse?

Tomorrowland commissioned a 200-page safety report called “Project Atlas” from the University of Antwerp’s Chair of Crisis Governance. Professor Hugo Marynissen and his team simulated an evacuation of 40,000 people from the main stage area in the worst-case scenario of a fire during peak attendance. The conclusion: all festival-goers would have reached safety within the European-mandated 8-minute evacuation window, well before heat radiation would become dangerous after approximately 15 minutes.

What’s Next

For the 2026 edition, Tomorrowland has implemented additional safety measures including dedicated “fire watches” — personnel specifically monitoring fire safety — additional hydrants behind the stage, reinforced fire-resistant underpasses, extra emergency lighting, and backup teams for critical safety functions. The festival continues this weekend at De Schorre in Boom, with construction of the new main stage already underway.

Despite the devastation, the fire has not diminished interest in the festival. Michiel Beers noted that 3.3 million people registered for the 2026 pre-sale, up from 1.6 million the previous year. “It’s strange to say,” he told HLN, “but for Tomorrowland it’s the best marketing to suddenly be on the news from Canada to New Zealand.”
