A large cement plant with sections of the old mining railway at the entrance. Several narrow-gauge locomotives are on display here and can be viewed.

You are in the middle of the pithead of the former "Walert" mine. For almost a century, from the 1880s to 1963, iron ore was mined here, both in the opencast and in galleries. At the time, the mine mainly supplied the factories of Rodange and Seraing in Belgium, where the ore was transported by rail. The site became a museum in 1973 and the use of the pithead facilities was changed: the first offices were converted into a brewery; the locomotive shed now houses the visitor reception; the playground occupies the former wood stock, while the red rocks of the opencast mine are slowly being reclaimed by vegetation. The most spectacular part of the mine is underground (44.5 ha concession). The guided tour begins in the Museum reception building. The train will then take you underground for a walking tour through the galleries, among the tools and machines of three generations of miners.

The wagon was probably used to dispose of slag. There is a pile of slag on the slope directly in front of it. If you look closely, you can see a whole lot more of it further down.
