Introduction
In the heart of Sardinia, nestled in the breathtaking Valley of Nuraghi, stands one of the most extraordinary testimonies of the Nuragic civilization: the Nuraghe of Santu Antine. Located in the municipality of Torralba, in the province of Sassari, this monument represents one of the most imposing and well-preserved examples of Nuragic architecture, dating back more than 3,500 years. With its majestic structure and numerous theories about its purpose, the Nuraghe of Santu Antine continues to fascinate archaeologists, historians, and visitors from all over the world.
The History of the Nuraghe of Santu Antine
The nuraghe was built between the 15th and 13th centuries BC during the Bronze Age by an advanced civilization that dominated Sardinia with a network of defensive towers, villages, and sanctuaries. Its longevity and state of conservation testify to the extraordinary engineering skills of the Nuragic builders. Although the name “Santu Antine” derives from the medieval period and refers to Saint Anastasius, the site has much older origins and represents one of the most significant megalithic complexes on the island.

Architectural Structure
The Nuraghe of Santu Antine is distinguished by its trilobate structure, consisting of a central tower (mastio) about 17 meters high, surrounded by three secondary towers connected by a massive bastion. Originally, the central tower could have reached a height of over 20 meters, making it one of the tallest prehistoric constructions in the Mediterranean. The mastio is built with basalt blocks perfectly fitted together without mortar, using the cyclopean technique typical of the Nuragic civilization.
The interior of the nuraghe features a series of corridors, niches, and chambers arranged on multiple levels, with a helical staircase carved into the thickness of the walls—a unique feature that suggests an advanced level of engineering knowledge. The internal chambers display the typical false dome (tholos) roof, a technique that predates classical vaulted constructions.
Theories About Its Use
Scholars are still debating the original function of the Nuraghe of Santu Antine. Some theories identify it as a military fortress due to its strategic location and imposing defensive walls. Others suggest it was a royal palace, inhabited by a tribal leader or ruling class, given its monumental size and well-articulated interior spaces.
Another fascinating theory proposes that the nuraghe served as an astronomical observatory. The openings and corridors seem to align with the summer solstice and other celestial events, suggesting a role linked to sun worship and time measurement.

Mysteries and Legends
Like any ancient structure, the Nuraghe of Santu Antine is surrounded by legends and mysteries. Some popular narratives speak of secret tunnels connecting the nuraghe to other Nuragic sites in the area. Other legends tell of a hidden treasure within its walls, never found, guarded by ancestral spirits.
Another mystery concerns the identity of the Nuragic builders. Some scholars hypothesize that this civilization had contact with other Mediterranean cultures, such as the Minoans or Mycenaeans, suggesting architectural and cultural influences that are still under study.
