Las Médulas is a historical site located in the province of León (Castile y León, Spain), which used to be the most important gold mine in the Roman Empire. The spectacular landscape of Las Médulas resulted from the "ruina montium", a Roman mining technique. This technique employed was a type of hydraulic mining which involved undermining a mountain with large quantities of water. One of the last mining fronts is situated in the place known as "La Encantada" (The Enchanted), an enormous entry to a collapsed gallery is depicted in this 170º vertorama. Las Médulas Cultural Landscape is listed by the UNESCO as one of the World Heritage Sites.
