A village of history and traditions, Bortigali is an ancient village that rises at the foot of the Marghine chain. Its territory is studded with the traces of the populations that first inhabited these places and have left precious remains of their presence, such as domus de janas (the mysterious 'fairy houses'), dolmens and giants' tombs, especially near Monte Santu Padre. Outstanding among them is the Nuraghe Orolo, one of the best preserved in the entire area, consisting of a main tower to which a bastion with two towers has been added on the front. In Bortigali, there is also still one of the few working water mills in existence. History here passes through architecture, traditions and... sound frequencies! In fact, Bortigali became famous in the 1940s because Italy's first free radio station, Radio Sardegna, was founded here. At first it broadcast from a truck and then from a cave: Radio Sardegna was the first to announce the surrender of the Germans and later became the Sardinian regional broadcaster.
