Museum of the Cockerill Mine at Ellergronn

Where? Centre d'Accueil Ellergronn, L-4114 Esch-sur-Alzette

Exceptional legacy from the mining era

Esch’s Cockerill mine played a major role in Luxembourg’s 19th-century economic boom.
The restored mining site is called « Katzenberg » at Ellergronn ­and is located in a building complex that houses a museum with numerous artefacts from the former iron industry. On the guided tour, as well as exploring the site of the mine, you will be travelling through time and discovering fossils, minerals, mining tools and numerous other genuine iron-industry artefacts. If you need a break in the fresh air, you will see how the former open-pit mines worked at the Ellergronn nature centre, and learn about their evolution into today’s nature reserve.

Languages offered: German, French, Luxembourgish
Book 15 days in advance.
