Nuraghe Mereu

Nuraghe Mereu is a Nuragic stone fortress hidden in the forests of the Supramonte, perched above the Gorropu canyon in the municipality of Orgosolo, Sardinia.

The tower sits on a rocky outcrop at 835 metres above sea level, deep inside dense woodland. Locals from the Barbagia region call it "nuraghe intro 'e padente" – the nuraghe inside the forest. The name Mereu comes from the Sardinian word for "white" or "clear," a reference to the pale limestone blocks used to build it. That bright stone is exactly what makes the ruin stand out against the surrounding greenery.

How do you get to Nuraghe Mereu?

Reaching the site means hiking through the Supramonte di Orgosolo, one of the wildest and least accessible mountain areas in Sardinia. The path cuts through forest, with a final rocky scramble before the tower comes into view. Booking a local guide is a good idea, since trail markings here are sparser than on Sardinia's more popular routes and the thick woodland makes navigation tricky. Sturdy hiking boots and plenty of water are essential, especially in summer heat.

What will you see there?

The nuraghe has a complex trilobate layout: a central keep (mastio) flanked by two secondary towers, all linked by a curtain wall. The main tower still preserves its tholos vault and rises to roughly five metres — an impressive height for a structure several thousand years old. A bastion is visible on the western side, and traces of the surrounding settlement survive nearby, with the remains of huts tucked into the trees. Not far from the tower stand a group of Giant's tombs, believed to belong to the same Nuragic community.

The real reward for the climb is the view. From the platform beside the nuraghe, the panorama opens onto the Gorropu canyon — one of the deepest gorges in Europe, carved into the limestone massifs of the Supramonte. The combination of prehistoric architecture and near-surreal landscape scale leaves an impression even on well-travelled visitors.

When is the best time to visit?

Spring (April to June) and early autumn (September to October) are ideal, when temperatures make multi-hour hikes comfortable and the Supramonte vegetation is lush but still passable. Summers in this part of Barbagia can be brutally hot, and forest shade alone isn't always enough — early-morning starts are strongly recommended. Winter makes the terrain more technically demanding, especially after rain, but the canyon and surrounding forests take on a strikingly raw character in the colder months.

Frequently asked questions

Can you drive to Nuraghe Mereu? No — the final stretch is on foot only, through forest and rocky ground. Parking is available some distance away, with a hiking trail covering the rest.

How long does the hike to the nuraghe take? It depends on the route and starting point, but given the rugged terrain, it's worth allowing half a day for the outing, with enough buffer to return before dark.

Is it worth hiking with a guide? Yes, especially for anyone unfamiliar with the Supramonte — the area is densely forested, poorly signposted, and easy to get turned around in without local knowledge.

What else is worth seeing nearby? Close to the nuraghe you'll find Giant's tombs and remains of a Nuragic settlement, while the Gorropu canyon itself is one of Sardinia's iconic trekking destinations, worth a separate, longer excursion.
