Fodor's Expert Review Monte Sirai
Just outside Carbonia and strategically positioned atop a plateau that provides views inland and far out to sea, the remains of one of Sardinia's most important Carthaginian military strongholds were discovered by chance in 1962. The walls of Mt. Sirai were erected around 375 BC, and they continued to function as impregnable fortress barriers until the Roman conquest in 238 BC. The ancient acropolis is spread across more than 400 acres, so bring your walking shoes. You can continue exploring at Carbonia's Museo Archeologico Villa Sulcis to view a large collection of artifacts, some of them more than 4,000 years old.
