It is one of the most unusual Sardinian religious buildings, probably one of the oldest, and it stands on the ruins of constructions dating back to the Nuragic age. The church of Santa Sabina, two kilometres from the village of Silanus, dominates a picturesque rural landscape, next to the single-tower nuraghe to which it gives its name. Inside it, there is evidence of thousands of years of human presence in the archaeological area. The sanctuary is of early Christian or Byzantine origin and it was later rebuilt in the 11th century.
Recently, during the works to check the condition of the foundations, basalt ashlars from the top of the Nuragic tower were uncovered, which had been used for the flooring. Deeper down, traces of masonry from the huts of a Nuragic village emerged, as well as numerous finds from the Roman era, providing evidence of the uninterrupted use of the complex. A fragment of the curved stele of a Tomb of Giants was also found.
