A small town in the metropolitan city of Cagliari, characterised by important pre-Nuragic and Nuragic archaeological sites (such as the nuraghes of Casteddu de Fanaris and Monte Idda, and the Domu de Janas of Sant’Iroxi).

On the ruins of what were once Roman baths, traces of which can still be seen, a church now stands.

Ticket prices vary depending on the type of visit. You can find all the latest information on the website: https://www.grottasangiovanni.com/.

According to legend, the Acquafredda Castle was built by the Gherardesca family, Counts of Donoratico, when they acquired southeastern Sardinia. In fact, in 1257, the fortress came into the possession of Ugolino of Donoratico, lord of the Cagliarani territory, immortalized by Dante in Canto 23 of the Inferno. However, the castle is older, as it is already mentioned in a papal bull of 1215. After Ugolino's death (1288), it passed into the possession of Pisa, then to the Aragonese (1324), and subsequently to several feudal lords until it was redeemed by Victor Amadeus III (1785). From the top of a mountain, the castle dominates the territory of Siliqua, four kilometers away. Climbing its slopes, the view sweeps from the green valley of the Cixerri to Cagliari, from the Marmilla to the Iglesias area. At dawn and dusk, their shadows extend across the valley.

The town's main church, with a modern appearance that barely catches the eye of travelers passing through Terraseo. There's a small fountain in the square for refilling your water.

If you're coming from Iglesias towards Terraseo, be prepared. The next few kilometers will be scenic but challenging, with gradients sometimes exceeding 10%.
