Gesico (Gèsigu in Sardinian) is an Italian commune of 714 inhabitants in the province of South Sardinia, in the subregion of Trexenta. An area inhabited since Nuragic times due to the presence in the territory of some nuraghi, in the Middle Ages it belonged to the Giudicato of Cagliari and was part of the curatoria of Siurgus. At the fall of the Giudicato (1258) it was conquered by the Pisans under the rule of the family of the Counts della Gherardesca, and then, around 1324, it passed to the Aragonese. The villa, which had sent its representatives to the parliament convened by King Peter IV the Ceremonious of Aragon in Cagliari in 1355, became a fief under the Aragonese and for a time was owned by the Carroz family. In 1368 it was a fief of the Puyalts, then of the d’Erils and the Sannas, and in the 18th century it was included in the marquisate of San Tomaso, a fief first of the Cervellons, and then of the Nin Zatrillas, to whom it was redeemed in 1839 with the suppression of the feudal system.
