Dudelange

The commune also includes the smaller town of Budersberg, to the north-west. The Mont Saint-Jean, close to Budersberg, hosts the ruins of a medieval castle. In 1794 the French Revolutionary Army committed atrocities against the local population in Dudelange, when they massacred 79 civilians.

Dudelange is an important industrial town that grew out of the three villages and a steel mill in 1900. The D in the name of the ARBED steel company, later merged into ArcelorMittal, stood for Dudelange. As well as the Dudelange Radio Tower, an FM radio and television transmitter, it is also the site of the Centre national de l’audiovisuel (CNA), a cultural institute founded in 1989 under the aegis of the Ministry of Culture in order to preserve, promote and exhibit Luxembourg's audiovisual and photographic heritage. The centre hosts a two-screen cinema, a restaurant and a library focused on the visual arts.

On 14 February 2017 the Dudelange train collision happened here.
