Su Nuraxi di Barumini: How to Read Sardinia’s UNESCO Nuraghe

A grassy hill until 1949, now a UNESCO site: how to read Sardinia's best-known nuraghe on a visit.

The short answer

Su Nuraxi, at Barumini in south-central Sardinia, is a complex nuraghe: a stone tower of the seventeenth century BCE, a bastion of four towers added later and a village of round huts lived in until the sixth century BCE. Until 1949 it looked like a grassy hill; since 1997 it has been a UNESCO World Heritage Site.

A hill that was hiding a castle

The people of Barumini called the rise outside town Bruncu Su Nuraxi, “the hill of the nuraghe”, without seeing much of one. Farm labourers working the land for its owner, Oreste Sanna, were the first to notice stonework poking through. Then, in 1949, torrential rain washed away part of the packed earth that covered it, and the archaeologist Giovanni Lilliu, who was from Barumini himself, recognised what was underneath. He excavated it between 1950 and 1957.

The name is plain Sardinian. In Campidanese, the dialect of southern Sardinia, su nuraxi simply means “the nuraghe”.

Two thousand years in one place

The core is a central tower built in the seventeenth century BCE, originally almost 19 m tall, with three chambers stacked one above the other. Later in the Bronze Age, four corner towers joined by a curtain wall were built around it, turning a tower into a small castle. Outside the walls grew a village of round huts, lived in from the thirteenth to the sixth century BCE, and people kept coming back to the site well into Roman and early medieval times.

A walk through it

Visits follow a set route with a guide, and it works well as a way of reading the building. You enter the bastion through a narrow doorway under a huge lintel. In the courtyard, find the well and the cuts made for drainage: in a dry landscape, controlling water kept the whole complex alive.

Inside the central tower, look up. The vault climbs inwards ring by ring until one stone closes it, and the walls are dotted with niches for storage. The stair hidden in the thickness of the wall shows you just how massive the masonry is. Finish in the village of round huts, and look for the meeting hut, with a stone bench running round the inside wall where people sat facing each other.

Why it is still standing

There is no mortar anywhere. The rooms stand because of weight, friction and tight joints: each ring of a vault leans a little further in than the one below, so the load pushes towards the centre until a capstone closes the top. Long blocks set deep into the walls bind the shell together. The builders worked in basalt, a hard dark volcanic stone, and set the biggest blocks with ramps, levers and sledges.

What was it for?

Several things at once, and differently over the centuries. The plan speaks of defence: height, thick walls, narrow entrances. Hearths, jars and worn floors speak of people living and storing food there. The meeting hut and the care given to thresholds suggest gatherings and ritual. Su Nuraxi is the place where you can see all of this together, and it has become the best-known symbol of the Nuragic world.

Before you go

The site is run by the Fondazione Barumini and can only be visited with a guide, in Italian, English or French. It is open all year and covers about 23,000 square metres of open country, so bring water and a hat in summer. Times change with the season, so check the foundation’s website before you travel. If you have already seen other monuments of prehistoric architecture in Europe, notice how Su Nuraxi combines tower, fortress and village in one place.
