⛏ Las Médulas

Las Médulas is a historic gold-mining site near the town of Ponferrada in the comarca of El Bierzo. It was the most important gold mine, as well as the largest open-pit gold mine, in the entire Roman Empire. Las Médulas Cultural Landscape is listed by UNESCO as a World Heritage Site. Advanced aerial surveys conducted in 2014 using LIDAR have confirmed the wide extent of the Roman-era works.
