⛏ Arenberg Pit

The Arenberg Pit of the Compagnie des mines d’Anzin is a former coal mine located in Wallers, in the Nord–Pas-de-Calais mining basin. Shafts Arenberg Nos. 1 and 2 were started in 1900 in the northeastern part of the commune, within an unexploited area of the Anzin concession. Shaft No. 1 served for extraction and Shaft No. 2 for ventilation. Coal extraction began in June 1903, and the site was named after Auguste Louis Albéric d’Arenberg, an administrator of the Compagnie des mines d’Anzin. The mine soon became one of the company’s major production sites. Residential areas with schools, a domestic science school, a church, and a community hall were built nearby. In 1936, Shaft No. 1 received a new headframe, replacing the older structure, and the conical spoil tip No. 160, known as Arenberg, increased in size.
