Considered to be one of the largest mining exploitation sites of the Roman world, mining at Tresminas began during the reign of Augusto (27 BCE - 14CE), and lasted through the time of the Seventh Severo. The activity was conducted through the open pit mining, which gave origin to the large craters dispersed throughout the current day landscape, which constitute hard evidence of the human effort employed in the site. Cutting across the vein, is a complex system of galleries opened for the transportation, removal and treatment of the minerals. These can still be visited today. The Archaeological Parque offers lookouts over the open pit, interpretive panels, pedestrian walkways with signs and picnic areas. Tour guides are required for visits inside the galleries.
