Wallonia In the past, Liège was one of the most important steel-making centres in Europe. Starting in 1817, John Cockerill extensively developed the iron and steel industry. The industrial complex of Seraing was the largest in the world. Although now a shadow of its former self, steel production and the manufacture of steel goods remain important.
