Mining ecomuseum of the Valley of Samuño, Ecomuseum in Langreo, Spain.
The Mining Ecomuseum of the Valley of Samuño is a heritage site that documents regional industrial history through a working mining railway and underground sections. The facility combines historic rail tracks, excavated passages, and a visitor center with displays of tools and working conditions.
The region was a major coal extraction center for over two centuries, fundamentally reshaping the landscape and local economy. The museum was established in 2013 to preserve this industrial heritage and make it accessible to the public.
The place tells the story of generations of coal workers whose labor and daily struggles shaped the region for centuries. Through displayed tools and photographs, visitors understand how mining influenced community life and local traditions.
Wear sturdy shoes and weatherproof clothing, as the visit spans roughly two hours and includes both above-ground and underground sections. Tours are conducted in small groups, so it is helpful to check in advance when guided sessions are available.
The visit descends roughly 30 meters below ground through the Emilia sinkhole, one of Spain's largest underground mining sections open to visitors. This subterranean railway route reveals the vast network of tunnels that once crisscrossed beneath the region.
