Ebbw Vale Steelworks was an integrated steel mill located in Ebbw Vale, South Wales. Developed from 1790, by the late 1930s it had become the largest steel mill in Europe. It was nationalised after World War II. As the steel industry changed to bulk handling, iron and steel making was ceased in the 1970s, and the site was redeveloped as a specialised tinplate works. It was closed by Corus in 2002, but is being redeveloped in a joint partnership between Blaenau Gwent Council and the Welsh Government.
