Known as the Sulcis Railway, this narrow-gauge line was built in the 1920s by the Ferrovie Meridionali Sarde (Sardinian Southern Railways) to connect the mining areas of Sulcis with coastal towns and ports of embarkation. The route passed through isolated landscapes and wooded valleys, serving villages and mines that are now partly abandoned. Today, bridges, tunnels, and disused stations remain, testifying to the era when the railway was the main means of communication for miners and goods in the southwest of the island.

Or the Menhir of Terrazzu (the location where it is located). A megalithic monument over 5 meters tall; its current height, however, is not its original height, as its top was damaged by lightning. It is said that it was planted in Terrazzu by the giantess Luxia, who was tasked with building a bridge between the island of Sant'Antioco and the mainland. Upon arriving, however, she saw that the bridge had already been built and, enraged, threw the boulder to the ground, where it can be seen today. In the small park where the menhir is located, there is also a bicycle repair and maintenance station sponsored by the Cammino di Santa Barbara, of which the monument is part.
