On the hillside of the Genna Serapis, the mine director Giovanni Antonio Sanna built his home, a hospital, guest houses, a hotel, and a laboratory in 1870. Today, they are one by one protected monuments that shape the village of Montevecchio.
The trip to the valley takes you to the remains of three mines in a row: Piccalìnna, the medieval-looking Sant'Antonio and Sartori.
