Orroli, the Nuraghe Arrubiu and the plateau above the Flumendosa

In the interior of south-central Sardinia, on the plateau overlooking the Flumendosa valley and its reservoirs, Orroli is best known for the Nuraghe Arrubiu, one of the largest nuraghe complexes (Bronze Age stone towers) on the island, named after the reddish lichen on its stones. The town hall is at around 500 metres.

The village is far from the cities: for major services and work people look to the nearby towns and, further away, to Cagliari, a long drive. The centre has traditional stone houses and newer homes, surrounded by pasture, scrub and woodland. Prices are very low, but buyers should look carefully at the condition of buildings, many of them closed for some time, and at the distance from services.

The population decline is steep: Istat, the national statistics institute, counted 1,956 residents in 2023, 18.4% fewer than the 2,397 of 2011. The average age is 51.1, above 48.1 for the province, and 32.5% are over 65. Foreign residents are very few, at 0.4%.

Like all of Sardinia, Orroli is in seismic zone 4 of the Civil Protection classification, the lowest, with an expected acceleration of 0.050 g. The practical advice is about upkeep: roofs, damp in stone walls and services.

For each address the report shows the official landslide and flood maps and the actual distance to schools, pharmacies and shops, useful in a village this far from the cities. Revenue Agency cadastral maps are published.

Key points

  • Plateau above the Flumendosa, Nuraghe Arrubiu.
  • Population down 18.4% since 2011.

Overview

Orroli is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 1,956 residents, ranked 40 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Orroli is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 18.4%. The estimated average age is 51 years, higher than the province average (48). 32% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.4% of the population. On average, a household has 2.1 members.

Landslide and flood hazard changes from one street to the next even within Orroli: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection.
