As a testament to Sardinia's ancient past, the Cagliari Archaeological Museum, located in the Castello district, offers a journey through 7,000 years, from the mystery of the nuraghi to Prehistory and the Early Middle Ages. Among its treasures are 33 sculptures of the Giants of Mont’e Prama, with another 11 on display at the Museo Civico Giovanni Marongiu in Cabras, where they were discovered in 1974.
At the heart of Marmilla, the Nuragic Complex "Su Nuraxi" in Barumini is the most significant monument of the Nuragic civilization in Sardinia, declared a UNESCO World Heritage site in 1997.
Continuing to the southwest coast, you can visit the archaeological site of Nora, an ancient city of Nuragic origin that later became Punic, and was once the capital of the Noritani people.
About an hour from Cagliari lies the Sinis Peninsula, where, in addition to the ancient city of Tharros, founded by the Phoenicians in the late 8th century BC, you can explore the town of Cabras with its Giants of Mont’e Prama and the city of Oristano, where you can admire the remnants of medieval walls and towers in the historic center.
Far from the bustling towns, along the winding road connecting Iglesias—a small medieval town worth visiting—to Fluminimaggiore, you'll encounter the fascinating Anatas temple, discovered by General La Marmora in 1836.
