Spread over a 7-hectare site in a thick cork and oak wood, this 17th-century BC nuraghic sanctuary comprises several religious buildings and circular village huts. The highlight is the sacred well temple, covered by a typical tholos and connected to a semi-elliptic amphitheatre. To make sense of the ruins, there are up to six daily guided tours; most are in Italian but tours in English and German are also offered.
