See main article: Cattenom Nuclear Power Plant. Cattenom is well known for its nuclear power plant, which was built from 1987 to 1992. An artificial lake has been introduced to cool the four nuclear reactors. The creation of this lake has led to the flooding of Ouvrage Kobenbusch, part of the Maginot Line.
