As the III. Reich invaded the Grand Duchy of Luxembourg in May 1940 in order to be able to advance further into France and Belgium, the Minett region was occupied by the French army mobile units. There were occasional skirmishes and fighting. A total of 59 soldiers from the 6th Regiment of the Algerian SpaHis, light scout troops, were killed in the area of Pétange, Differdange and Lasauvage. This plaque commemorates their victims. Another plaque also commemorates victims among the civilian population who had to pay with their lives for helping to resist the occupiers.

This extraordinary collection of fossils and minerals is the result of years of compilation by collector Eugène Pesch. The museum named after this Luxembourger from Differdange also offers a reconstruction of a mining tunnel and an entire exhibition on the difficult working conditions that miners faced in the early 1900s.
