Santa Sabina, Romanesque church in Silanus, Sardinia, Italy

Santa Sabina stands on the outskirts of Silanus along the road to Macomer, with a large circular central body topped by an ovoid dome and a iron cross, flanked by two smaller rectangular rooms with wooden double-pitched roofs. The lower walls are black basalt reused from the nearby nuragic complex, while the upper parts are white limestone, a two-tone effect less visible on the rebuilt right room. The main entrance has a 1.90-metre projecting porch with a round arch and a monolithic basalt lintel; two hollowed basalt blocks beside it probably served as holy water stoups.

The construction date is uncertain: some scholars place it in the early Middle Ages, using basalt from the nearby nuraghe and giants' tomb, with a renovation in the second half of the 11th century; others date it to the 10th–11th centuries. It probably belonged to the Benedictines, but all historical documents are lost. In 1987, consolidation work revealed nuragic hut walls with Roman additions beneath the floor.

The church belongs to the nuragic complex of Santa Sarbana, and its name recalls Saint Sabina. The black basalt blocks in the lower walls were reused from the nearby nuraghe and giants' tomb, while the white limestone upper sections create a visible two-tone effect. The threshold between the central and left rooms is a stele probably taken from a giants' tomb.

Access to the church is on foot through the village of Silanus in central Sardinia, which is reachable by car from nearby towns. Visitors should wear respectful clothing when entering, as this is an active place of worship.

The threshold between the central and left chambers is a reused stele, probably from a nearby giants' tomb. Consolidation work in 1987 also uncovered walls of nuragic huts with Roman additions, plus pottery and bone fragments, beneath the original floor.
