The Musée de la mine Cockerill (Cockerill Mine Museum) displays fossils, lamps and mining tools, as well as other artefacts from the life in the miners. It was created by the Entente Mine Cockerill Esch sur Alzette, a non-profit organisation of volunteers, who preserve the local mining heritage. They work for the preservation and promotion of the Katzenberg mining site in Esch-sur-Alzette. They also offer guided tours for groups of eight people or more. The Cockerill Mine Museum is a site on the European Route of Industrial Heritage.

The museum shows all the typical machinery and tools of a working mine. There are hammers, chisels, lamps of all kinds, helmets and protective gear. The miners used carbide lamps in the early years, but in the 20th century they were replaced by electric lamps with lead batteries. The museum has a station in which the lamps were charged for the next shift. There are also some smaller machines, for example a short piece of railroad tracks with a transport cart and a special saw to cut the rail to the right length by hand. There is also a section of communication gear, which were simple but robust telephones which were connected by copper wires. Henkelmänner are enamelled or painted sheet metal containers, which were used to transport lunch into the mine for the lunch break. One of the highlights is a miner in full gear who drills a hole in the ceiling with a pneumatic drill to place ceiling anchors. Another section is dedicated to the use of explosives, boxes for dynamite or other explosives, ignition cables and machines. A manual siren was used to announce the detonation. The collections also includes fossils and ore specimens from the mined Middle Jurassic limestones.

The Waschkaue, the German term is also used in Lëtzebuergesch, is the room where the miners changed into their working clothes. It is rather small but very high, so there are no lockers, insted each miner hat a chain with hooks, on which the working clothes were hanging, and which was pulled to the ceiling. When they changed they lowered the hooks with the chain, put there normal clothes on the hook and pulled them back to the ceiling. At the end of the shift they showered and then changed back. The room is part of the museum and the walls are used for the exhibition of historic photographs. The blacksmith's shop is not only in working condition, it is actually used by the members of the society to repair broken tools, and show the visitors how this work was done.

The adit of the Grube Katzenberg is accessible on guided tours only. However there is no underground tour, only the museum and the open air exhibition of heavy machinery and mine trains. On special occasions train rides are offered.

The Grube Katzenberg is also known as Grube Collart. Located in the Höhl valley south of Esch an der Alzette, there are two tunnels. The mine hat no shaft, it was mined horizontally and the ore was transported by train to the
