The first human settlement in the area of Segariu, a municipality in South Sardinia, date back to Prehistory, as attested by the finding of a Neolithic village, composed of five huts, in the Costa Facci e Bidda site, in the north-east of the municipality. Many objects were found: pottery, obsidian tools, but also objects related to the metallurgical production and leftovers of a meal (mainly bones of domestic animals and shells of sea molluscs).
A figurine of a sitted female divinity in quartz sandstone was found in the Cott’e Baccasa area. It is seated and has folded arms to the breast, pronounced buttocks and voluminous thighs. The face has the typical T-scheme in relief and a nose with alettes; the figurine dates back to the Middle Neolithic (4800-4300 BC) and is attributed to the cultural field of Bonu Ighinu. It is currently on display in the National Archaeological Museum of Cagliari.
Among the evidences of human presence in the pre Nuragic era there is the necropolis of Sa Tumba, on the border with Furtei, consisting of four domus de janas.
The Nuraghe Fraga Morus dates back to the Nuragic period. It was a single tower nuraghe of which only the ruins of the perimeter walls remain nowadays, and the Nuragic complex of Saint Antonio, only partially brought to light, which dates back to the Nuragic period. It’s characterized by a quadrilobate structure, with the central keep and four lateral towers, located near the village.
Traces of a vast settlement of the late Punic period were found in the Eastern area around the nuraghe, but also inside it.
