Rome, August 9, 2026 – The Europe Today: Italy has marked the 70th anniversary of the Marcinelle mining disaster, one of the deadliest industrial accidents in post-war European history, commemorating the 262 miners who lost their lives at the Bois du Cazier coal mine in Belgium in 1956.
The disaster occurred on the morning of 8 August 1956 at the coal mine near Charleroi in Belgium’s Hainaut province. A hoist was activated before a coal wagon had been fully loaded into the lift cage, severing an electrical cable, an oil pipe and a compressed-air line. The resulting fire spread through the mine’s wooden structures and upper galleries, while smoke and carbon monoxide trapped workers more than 1,000 metres underground.
Of the 274 miners who were underground at the time, only 12 survived. Rescue operations continued for two weeks before a returning rescuer confirmed on 22 August that those remaining underground had perished.
The tragedy claimed the lives of 262 miners, including 136 Italians, as well as workers from Belgium, Poland, Greece, Germany, France, Hungary and other countries. Many of the Italian victims were migrant workers who had travelled to Belgium under a 1946 bilateral agreement that linked Italian labour to coal supplies for Italy.
Around 140,000 Italians travelled to the Walloon coalfields between 1946 and 1956, with many workers facing difficult living conditions and discrimination in housing.
The disaster was followed by legal proceedings. A trial court acquitted all defendants in 1959, while an appeals court in 1961 sentenced the mine manager to six months in prison, suspended, and imposed a fine, while acquitting the other defendants. The former Bois du Cazier mining site has since been transformed into a museum and is recognised as a UNESCO World Heritage site.
The 70th anniversary carries additional significance this year as 8 August has been designated a new annual European Day for the Victims of Workplace Accidents. The initiative seeks to preserve the memory of workers killed in workplace disasters and reinforce the importance of occupational safety across Europe.
The anniversary commemorations in Italy and Belgium serve as a reminder of the human cost of industrial disasters and the contribution of migrant workers to Europe’s post-war reconstruction.
