Nuraghe Su Nuraxi, Nuragic stone tower in Siurgus Donigala, Sardinia, Italy
This archaeological complex features a central tower surrounded by defensive walls and smaller structures, all built from large basalt blocks using dry stone techniques without mortar.
Constructed around 1500 to 1300 BC during the Nuragic civilization, the fortress was inhabited for centuries and underwent multiple phases of expansion and restoration over time.
The site represents the advanced engineering skills of Nuragic people, who quarried, transported, and assembled massive stones to create megalithic structures that served as symbols of political power.
Guided tours are available year-round through the on-site museum, with spring and early fall offering the most comfortable visiting conditions for exploring the stone ruins and learning about construction techniques.
The site lies in Siurgus Donigala, not Barumini; the Barumini nuraghe of the same name is a separate monument. Here the mound of stacked grey, brown and tan stones rises in stepped tiers, with metal railings along part of the upper edge and a narrow stairway. The lower slopes are looser rubble spreading outward.
