The outcropping rock on the hill of San Gemiliano supports the archaeological complex of S'Ortali 'e Su Monti, where over four thousand years of continuous occupation are clearly stratified within the municipal territory of Tortolì.
This fundamental site synthesizes the entire prehistoric trajectory of Ogliastra, juxtaposing the presence of Neolithic domus de janas and menhirs with the imposing Bronze Age structures that dominate the plain all the way to the sea.
The heart of the settlement includes a complex nuraghe enclosed by a bastion and an articulated village of circular huts. A short distance away stands the giants' tomb, built with orderly courses of granite blocks and enclosed by a wide semicircular exedra that welcomed collective burial rituals, while two large aniconic menhirs flank the access path as silent witnesses to the area's oldest lithic cults.
From the top of the hill, visual control swept easily over the entire Gulf of Arbatax and the rich, fertile lands of the Tortolì plain. The direct proximity between the living spaces, the fortress, and the funerary areas makes S'Ortali 'e Su Monti an ideal case for understanding the social, economic, and spiritual organization of ancient Sardinian communities settled along this entire sector of the eastern coast.
