Originally the village stood a couple of kilometers from the current location, the ruins are located near the rural church of San Lussorio, near the banks of the Flumini Mannu (more formerly Ptolemy refers to "Rivus Sacer" "sacred" or "Hierus") where the waters of the Rio Piras and Riu Bruncu Fenugu meet. The homonymous nuraghe (Santu Sciori) and a Roman bridge (still standing) called "Su ponti de sa baronessa" testify to the ancient origins of the village. During the Middle Ages it belonged to the giudicato of Arborea and more precisely to the curatorial office of Bonorzuli, the ancient centre was destroyed by the Saracens and rebuilt in its current position. At the fall of the judiciary (1420) it became part of the marquisate of Oristano, and from 1478, at its final defeat, it passed under the Aragonese dominion. The Aragonese incorporated the town into the county of Quirra, which was transformed into a marquisate in 1603, together with the barony of Monreale. Also in the Aragonese period, the town was first a feud of the Carroz, then of the Centelles and finally of the Osorio de la Cueva, to whom it was redeemed in 1839 with the suppression of the feudal system. In 1584 it was sacked by the Moors and the town was abandoned, the historian Vittorio Angius wrote: "... the barbarians were led there by a Sardinian renegade, [...], except for the people saved by the escape, the others were massacred or taken in slavery".
