The audio tour begins on Neustraße, also known as Nieuwstraat, which today connects Kerkrade and Herzogenrath more than it separates them. It leads through Merkstein and Alsdorf, covering a total of about 20 kilometers to Baesweiler-Setterich. Along the way, a stop at the Energeticon experience museum is worthwhile, as it impressively demonstrates how significantly the northern district of Aachen was shaped by coal mining and how indispensable labor migration was for this industry from the very beginning. A unique aspect of the Wurm region was that even small-scale immigration often had a transnational character. The use of forced laborers during World War II marked the darkest chapter of the arduous underground work. The migration history audio tour from Kerkrade to Setterich was funded in 2023 by the Innovation Fund for Continuing Education of the Ministry of Culture and Science of North Rhine-Westphalia.
