Along the provincial road SP 2, a few kilometers from the junction for Uta in the direction of Siliqua, on the top of a promontory that extends for about 4 hectares at 128 meters above sea level, is the archaeological area of Su Niu de Su Pilloni (3rd millennium B.C.), one of the most important archaeological sites in the territory of Uta. It is an impressive fortified area consisting of mighty megalithic structures characterized by their leaning against the natural rock with which they form an articulated defensive system. Strategically positioned at the highest points are numerous masonry walls pertaining probably to ancient torricapanna. Counted among the so-called “walls,” the area represents a unicum of its kind also because most of the complexes pertaining to this typology are documented exclusively in central and northern Sardinia.
