At Barumini there is a special atmosphere: since prehistoric times the present village was the centre of power and the reference point for a rich and fertile territory, the Marmilla. On Nuraxi, the most imposing (and best preserved) of the thirty Barumesi nuragic sites, as well as the most important legacy that the civilization 'of the towers' has left us, stands witness to the town's importance. The archaeological area includes a complex nuraghe and an extensive village of huts, a unique place, which UNESCO declared a World Heritage Site in 1997. The impressive site came to light thanks to the excavations conducted in the mid-20th century by Giovanni Lilliu. The cultural center located a short distance from the nuraghe was named after 'the father' of Sardinian archaeologists, where events, exhibitions and concerts are held.
Su Nuraxi, made of basalt, volcanic stone from the nearby Giara park, has a stratification of two thousand years, from the 16th century BC to the 7th century AD. The complex consists of a central tower (keep) and four corners connected by a bastion, surrounded by a labyrinth of 50 huts, wells and cisterns.
