The Bois du Cazier coal mining site portrays the working classes and immigration to Wallonia (Belgium) in the 20th century. In 1956, the entirety of the site, from the pithead to the slag heaps, was the scene of a disaster in which 262 people of 12 different nationalities died. Whilst mining activity stopped in 1967, since 2002 the site has been transformed into a museum dedicated to the coal, iron and glass industry. It recalls European solidarity as demonstrated in the aftermath of the 1956 disaster which also triggered the creation of a health and safety body by the European Coal and Steel Community.
