A people who lived in symbiosis with nature, who expressed their spirituality venerating water, who constantly improved their skills in crafting stone and metals. Between Ogliastra and Barbagia, in the domain of Villagrande Strisaili, the riu Pira ‘e Onni valley is home to an intricate and fascinating archaeological complex many of whose characteristics can be ascribed to the Nuragic civilisation. It is called s’Arcu 'e is Forros, a symbol of the evolution of cultural characteristics from the Bronze to the Iron ages, and of relationships with civilisations far beyond Sardinia.

It’s a village/sanctuary built over a previous settlement of huts on a plot of land bordered by two streams. The sacred and residential areas include three temples, two areas with huts and, not far away, a three-lobed nuraghe.
