A fortified town with imposing towers and 16th century walls, it is set in an environmental context of great value including Porto Conte Park and Capo Caccia-Isola Piana Marine Reserve. The historical town center, with its architectural features and charming alleys, is a small jewel set in the land of Sardinia.
