As many people notice, the Sardinian landscape is dotted with an endless number of ancient and fascinating stone buildings, many of them ruined by the action of natural forces and many still showing with proud their noble origins.
There are at least 7000 Nuraghi in Sardinia, the ones censed so far. However, many more have still to be discovered as currently hiding their secrets underground.
There are so many unanswered questions about the Nuraghi, how they were built, who built them and why? There are still not unique answers to those questions by the archaeologists. Some believe they are a place of worship, others think they are a fortress to protect from enemy’s attacks. For others researchers those complex constructions were the assembly point for the people living in the joined villages.
Whatever the answers might be, the Nuragic civilization was very well organized for its time and definitely knew complex building techniques.
The Nuraghi are still full of mysteries and open questions. What we do know is their age: they were built during the Bronze Age, starting 1900BC and were occupied up until 500BC approximately. We do not know much about the Nuragic civilization that built and occupied those massive constructions. Bellowing to them we have found lovely artefact called “bronzetti” which are elegant small sculptures representing animals, warriors, farmers and other elaborated figures.
Some of the Nuraghi have almost 4000 years of age and they still have a strong and impactful presence. There is a large variety in the construction complexity; some are simple circular towers which have the shape of a truncated cone. They are made with stones of considerable size progressively smaller as it increases the height. Other Nuraghi have a large number of internal chambers and sophisticated communicating structures like the one called Palmavera, close to Alghero, the Nuraghe Arrubiu di Orroli, the Nuraghe Santu Antine in Torralba, and many more.

The Nuraghe complex at Barumini, called “Su Nuraxi” is one of the finest and most complete examples of this remarkable form of prehistoric architecture.
For this reason it was declared World Heritage by UNESCO in 1997. It is still preserved in excellent conditions, especially the proximity of the huge fortress, which consists of several towers and communicating tunnels. It is an exceptional construction that still amazes its visitors. Particularly the central tower which was originally about 20 meters in high and surrounded by four additional towers. The entire area was then surrounded by other seven towers so that the entire complex had a hexagonal shape.
