Many dips invite you to play around on your bike. Nothing special, but quite nice if you happen to be passing through.

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.
