The small country church of medieval origins stands on a gentle knoll in the hamlet of Flumentepido. Dating from the 11th century, it boasts simple but charming Romanesque architecture, with a single nave without an apse. Its history is linked to the Benedictine monks of Montecassino who became its owners in 1066 thanks to a donation from the judge of Cagliari, Orzocco Torchitorio I. During the visit, don’t miss the remains of the nearby monastery, shrouded in nature, and the portico enriched in the 17th century with columns containing Roman milestones, witnesses of the ancient via Sulcitana, that is, the road axis that connected in Roman times the two cities of Karales (Cagliari) and Sulci (Sant’Antioco). The interior of the church, though bare, retains the original red trachyte masonry and small molded windows that tell stories of past eras. It has a rectangular plan with a single nave with a gabled roof and wooden ceiling supported by trusses, and in the back wall is the niche that housed the simulacrum, now kept in the nearby chapel of St. Anthony, along with the stoup. The facade is sober, with a small bell gable.
