Brussels authorities have opened an investigation into whether fireworks from a U.S. embassy celebration caused damage to the Royal Museum of Art and History, one of the buildings within Parc du Cinquantenaire, following the largest diplomatic reception ever staged in the Belgian capital.
The June 28 event, organized by U.S. Ambassador Bill White to mark 250 years of American independence, drew more than 8,800 invited guests and featured a large fireworks display beneath the park's iconic triumphal arch. The celebration reportedly cost around €5 million, with White raising the funds from approximately 220 Belgian and American companies.
Belgium's Buildings Agency confirmed that "fireworks debris was found on the roof" of the museum building and that "certain limited areas of the roof appear blackened." The agency said analyses are still ongoing before it can comment on the scope of any necessary repairs.
What the Left Is Saying
Belgian Buildings Minister Vanessa Matz urged caution, saying investigators must first determine whether any damage was caused by the fireworks display or by a severe thunderstorm that swept across Brussels the night before the celebration. "We need to establish the facts before making any determinations," she said in a statement.
Flemish newspapers De Standaard and Het Nieuwsblad first reported on the investigation, raising questions about whether proper permits were obtained for the fireworks display near historic structures within the park.
What the Right Is Saying
Ambassador White defended the event's execution, writing on X that his team is "in immediate contact with the Belgian company that was hired to coordinate all event logistics, including the fireworks company." He said the contractor would "remediate where it is required" and insisted that "Cinquantenaire has never looked any cleaner than it was the day after we cleaned up after our event," posting photographs of the park appearing immaculate.
The embassy emphasized that the celebration was one of the most significant diplomatic events ever held in Brussels, showcasing U.S.-Belgian commercial and cultural ties through contributions from more than 200 companies from both nations.
What the Numbers Show
8,800: Number of invited guests who attended the June 28 celebration at Parc du Cinquantenaire.
€5 million: Approximate cost of the event, funded entirely through corporate sponsorships from roughly 220 Belgian and American companies.
1: Number of Belgian government agency currently conducting an investigation into potential damage to museum structures.
The Bottom Line
The investigation remains ongoing, with Belgian authorities expected to release findings once analysis of roof conditions is complete. The incident highlights the diplomatic sensitivities involved in large-scale celebrations at historic sites, particularly when foreign embassies organize events that require coordination with local officials and preservation experts. Ambassador White has maintained that his team acted responsibly, while Belgian regulators are still working to determine whether any remediation will be required.
