Siris

A Hilltop Village in the Upper Marmilla Region

Siris is a small village situated in the upper Marmilla region at an altitude of 161 meters above sea level, nestled at the foot of Mount Arci and surrounded by dense forests of holm oaks, downy oaks, and cork oaks. The municipal territory features an irregular geometric profile with sharp altitudinal variations and a fascinating landscape that includes a small tableland (giara) crowned by the Nuragic site of Tanca Manna. The local portion of Mount Arci extends to the cliffs of Su Columbariu and is characterized by trachyte rock formations and numerous caves, the largest of which is the Rio Bingias cave near a renowned oligomineral spring.

Etymology and Economy

The origin of the name is uncertain, potentially deriving either from the Latin gentile name Sirius (referring to a Roman estate or villa owner) or from the Greek Xiris, which denotes the Iris germanica flower widely distributed throughout the area. The local economy is primarily based on agriculture—cultivating cereals, wheat, forage, vines, fruit orchards, and olives—along with sheep and pig farming. Siris is particularly famous for its autumn harvest of quince (mele cotogne), which is traditionally used to prepare jams, jellies, and preserved fruit specialties.

Historical Overview

The area has been inhabited since the Nuragic period, as evidenced by surviving nuraghi. During the Middle Ages, Siris belonged to the Giudicato of Arborea within the Marmilla curatoria and was among the villages that signed the 1388 peace treaty between Eleonora d’Arborea and John of Aragon. Over subsequent centuries, it passed through various feudal jurisdictions—including the Carroz, Centelles, Borgia, Català, and Osorio de la Cueva families—until the abolition of feudalism in 1839. After being merged with neighboring municipalities during the fascist era, Siris was re-established as an autonomous municipality in 1961 and became part of the Province of Oristano in 1974.

Architecture and Religious Heritage

The village preserves its traditional stone houses with fine portals in its oldest core. Key landmarks include:

• Parish Church of San Sebastiano Martire: Built in 1958 and redesigned by Oristanese engineer Carlo Cherchi with architectural features inspired by the Dominican church in Cagliari, featuring an arena-stone façade, a square bell tower with a pyramidal roof, and housing 17th-century wooden statues of Saint Anthony of Padua and Saint Vincent the Martyr alongside precious historical silver.

• Church of San Vincenzo Diacono Martire (Cresia de Santu Bissenti): A restored country sanctuary of uncertain ancient origin featuring a central-plan structure, wooden roofing, and an ancient stoup, which houses a treasured relic of Saint Vincent.

Traditions and Festivals

Siris maintains a strong calendar of civil and religious community gatherings:

• Feast of Saint Sebastian (January 20): Celebrated with a traditional community bonfire on the eve and a solemn procession through the town center.

• Feast of Saint Vincent (August 31–September 1): The major village festival held at the country church of San Vincenzo, concluding in early November with the Inserru de Santu Bissenti, a procession returning the saint’s statue to the parish church.

• Dairy Products Festival (Sagra dei prodotti caseari): A spring event celebrating local cheeses produced from free-roaming sheep herds, featuring a traditional cheese-wheel throwing competition (Lancio della forma di formaggio).

• Quince and Berries Festival (Sagra delle mele cotogne e frutti di bosco): Held in mid-November to celebrate local culinary products, particularly dishes and preserves made from quince.

• The Pinnetti of Inus: Modern reconstructions of traditional Sardinian shepherds’ stone-and-wood temporary dwellings (pinnetti) located in the Pranu Sibiriu locality.
