It is a natural open-air museum that embellishes the coast of Golfo Aranci, in Gallura. The promontory of Capo Figari, along with the islet of Figarolo in front of it, have been declared a Site of Community Importance and are treasure troves of biodiversity. You can get to the promontory via the beach of Cala Moresca, a ‘gem’ set in a little bay and cooled by a pine forest. The summit of the promontory is just over three kilometres from the cove and, at the top, at a height of 350 metres, are the remains of the Naval Semaphore, inaugurated in 1890, purchased by the Ministry of Defence 15 years later and made famous in 1932 by Guglielmo Marconi, who built a shortwave radio link there, connecting it to the transmitter in Rocca di Papa, near Rome. From up here, you can enjoy a breathtaking view: to the south, you can see the entire gulf of Olbia, with Capo Ceraso and the island of Tavolara, while to the north, you can see the islands of Soffi and Mortorio with the Costa Smeralda in the background.
