Blegny-Mine is one of the four Walloon Mining Sites of Major Archaeological Importance inscribed on the UNESCO World Heritage List.
The mine remained operational until 1980, making it the last coal mine to close in the Liège basin.
The underground tour reaches depths of 30 and 60 meters below the surface using original cage elevators.
The temperature underground remains constant at approximately 13°C throughout the year regardless of external weather.
The site operates an original steam-driven machine that is still kept in working order for demonstration purposes.
The coal washing process visible at the site was a vital component for preparing raw coal for industrial steel production.
The site archives contain extensive records of the international labor force, including Italian, Spanish, and Greek workers who immigrated to work in the mines.
The spoil tip, the artificial hill created by mine waste, has been reclaimed by nature and now serves as an ecological trail.
Blegny-Mine is a preserved industrial coal mine site in Belgium recognized as a UNESCO World Heritage site. Visitors can descend 30 and 60 meters underground via the original mine shaft to view working coal extraction equipment. The site features an extensive collection of restored mining machinery and tools used throughout the 20th century. Above ground, the facilities include a washery, a sorting plant, and a power plant that demonstrate the full industrial coal cycle. The site serves as a center for industrial archaeology, maintaining functional historical equipment for public demonstration. Educational exhibits provide insight into the living and working conditions of miners during the peak of the Belgian coal industry. It remains one of the few mining sites in Europe where the complete infrastructure from extraction to processing is preserved in situ.
