a town of Belgium, on the right bank of the Meuse, in the province and 3 miles S.W. of Liège. It is chiefly remarkable for its immense iron-works, among which is probably the most extensive manufactory of machinery in the world. It occupies the former palace of the bishops of Liège, which has thus lost all its palatial and ecclesiastical aspect. Seraing has also iron-furnaces, forges, and coal-mines, employing from 3000 to 4000 hands, and a large number of steam-engines. Pop. 4857.
