From a small hill, it stands with all its immensity, dominating the Tirso Valley: it is one of the largest and best-preserved Bronze Age monuments in central Sardinia. The nuraghe Santa Barbara - with the same name as that of Macomer – stands in the locality of Tanca sa Cresia, in the territory of Villanova Truschedu, a small village twenty kilometres from Oristano: you can get to it from the provincial road SP 9, which passes by the ancient Sanctuary of San Gemiliano, after crossing a bridge over the river and walking along a short path. It is a shining example of an ‘a tancato’ building, consisting of two circular towers, a larger original one and a smaller one that was added later, connected by a curtain wall that encloses a courtyard, bordered by embedded stones.
