The Bois du Cazier stands as a poignant reminder of Belgium's industrial past and the tragic mining disaster of 1956, which claimed the lives of 262 miners. Today, it serves as a significant industrial heritage site, offering visitors a glimpse into the coal mining history and the evolution of industrial technology. Recognized by UNESCO as a World Heritage Site, it also features an Industrial Museum and Glass Museum, contributing to the European Route of Industrial Heritage. The site not only commemorates the past but also educates on the importance of workplace safety and the contributions of migrant workers to Belgium's economy.
