From Roman times, ore such as silver bearing galena and lead was extracted from the Arditurri mines making them one of the most important ancient mines in Hispania along with Las Médulas mines in Leon and those of Cartagena or Rio Tinto. The mines were abandoned by the Romans in the 5th century, but were exploited again from the Middle Ages until the 1980’s for iron ore making them among the very few in Spain that have been in use for over 2,000 years almost without interruption.
