The area's 3000-year mining history is explored at this intriguing industrial site, which sits a few kilometres inland from San Vincenzo. Here you can explore the ruins of the 14th-century mining town Rocca di San Silvestro, reached via an underground train that passes through the Temperino copper and lead mines. Guided tours depart roughly hourly.
Around 50m before the turn-off to the park entrance, a sunken lane on the right signposted 'forni fusori ' leads to the remains of some Etruscan smelting ovens, once used for copper production.
