Athus is a town in the Aubange municipality of the province of Luxembourg, in south-eastern Belgium. It is located in the far south of the country, just near the borders with France and Luxembourg. It is a French speaking city, though the traditional language is Luxembourgish but that is less and less used nowadays. The city was famous during the 19th and 20th century because of its steelworks factory which was bankrupt in 1977.
