A temple built on on the summit and southern slopes of a hill, in the periphery of the modern village, is indicated by an altar carved from the bedrock, as well as by traces of blocks which costitute the external walls. A preliminary excavation carried out in 2000 allowed us to work out the orientation and the perimeter, without throwing much light on the internal arrangements. The second campaign, recently concluded, concentrated on the highest point of the slope, where a certain number of systematically arranged rooms has been revealed, built in stone walling with an earth mortar. Unique in Sardinia both for its curious construction and for its siting and its huge size, the temple is dedicated to Juppiter, as the inscription -IOVIS' carved into one of the short sides of the altar demonstrates. A second inscription, on the opposite side, is unfortunately illegible. The temple can be dated to the second century b.C. by finds of coins, black glaze pottery and Greco-Italic amphorae, and it does not seem to have been in use for very long. A burial cut into the destruction layers of the temple shows that the area was occupied in the early Middle Ages. The individual, probably a woman, wore a ring whose centre was decorated -ad occhi di dado', with small concentric circles, typical of the period.
