Extracted iron ore used to be transported along a 1.4 kilometre route, which connects the mine to the "Fond-de-Gras".

The Lasauvage mine was in use until summer 1978. Around 200 people worked underground towards the end of its activities.

For the past 30 years, the non-profit organisation "Minièresbunn", which is made up of 20 volunteers, has been showing visitors how the mine used to be operated.

Between May and September, people are thus able to take train tours across the mine.

Although no iron ore is being extracted from the mine anymore, it has recently been repurposed.

14,000 bottles of sparkling wine from Schengen were transported underground, where they will be stocked until the end of the year. Since the mine has a constant and low temperature, it is a perfect wine cellar.

The link with Schengen was originally established through the Collart family. Marc Collart used to be the director of the Esch-sur-Alzette mine until his death in 1941 in the Moselle village.
