The archaeological site "Su Nuraxi " (the nuraghe) of Barumini , declared in 1997 by UNESCO World Heritage Site, only 3 km from Tuili, is definitely the most important monument of the Nuragic civilization. Characteristic above all because it combines the enormous fortress with a vast and labyrinthine village with very narrow lanes and court houses, wells, cisterns and huts for meetings, linked to a mysterious history that began 3500 years ago.
During the visit you enter the fortress, passing through narrow tunnels built into the walls built with huge boulders, in an impressive cyclopean environment extremely interesting and suggestive. Positioned in such a way as to dominate the surrounding plains, is a nuraghe defined quadrilobate, with the oldest part, the central tower, originally more than 19 meters high, consisting of three overlapping tholos (the typical nuragic chambers) and dating back to 1478 BC, date obtained by analyzing with a carbon 14 a piece of olivaster found interlocked between the large basalt boulders that make up the structure. The four towers that surround the central keep, positioned in the four cardinal points and originally built on two floors, were presumably built around the XIII century BC. Another clearly visible element is the wall, often about 3 meters, which completely removes the bastion, built around the eleventh century. a.C., perhaps to reinforce the structure. From this moment on, to enter inside the Barumini Nuraghe, one had to reach a small entrance door positioned about 7 meters in height, making "Su Nuraxi" in the eyes of the enemies, an impregnable fortress. Even today, after the excavations carried out by the archaeologist Giovanni Lilliu in the 50s, the only entrance to the fortress remains that "raised door". Now included in the admission ticket, you can visit the Lilliu Service Center with temporary and permanent exhibitions and the Casa Zapata museum, an ancient noble building built using the nuraghe "Su Nuraxi e Cresia", which can be visited from inside the building by footbridges and glass flooring. The museum also preserves important finds found in the nuraghe of Barumini Su Nuraxi as well as the Historical and the Ethnographic section.
