Su Nuraxi is a nuragic archaeological site in Barumini, Sardinia, Italy. It was inscribed on the UNESCO list of World Heritage Sites in 1997 as Su Nuraxi di Barumini.
Su Nuraxi simply means "the nuraghe" in Sardinian.
The complex is centered around a three-story tower built around the 16th century BC. At this site Italian archaeologist Giovanni Lilliu discovered a fortified village that at times had been covered by ground and had become a hill. He did the first excavations here in the 1950s.
This site would become important to the timeline of Sardinian civilization: "The relative chronology of Sardinian prehistory is largely based on the first modern excavation of a nuraghe at Su Nuraxi, Barumini. Giovanni Lilliu . . . used a combination of structural phases and pottery typology to construct a general Nuragic sequence."
