Isili, the Sarcidano plateau and the Is Paras nuraghe

In the heart of Sardinia, on the Sarcidano plateau, Isili is a local centre for the surrounding villages, with secondary schools and offices that serve a wider area than the town itself. It lies at around 500 metres among flat uplands and low hills, and its best-known sight is the Is Paras nuraghe, a Bronze Age stone tower famous for its unusually tall vaulted ceiling.

The property market is that of an inland town: family houses in the centre, often in need of updating, and newer homes on the edges. The big cities are a long way off, so people who choose Isili usually work locally, work remotely or are returning to their family roots. Climate zone D means winters with some cold, windy days, so windows and heating matter.

Istat, the national statistics institute, records 2,443 residents in 2023, down 14.0% on 2011. The average age is 50.9, above the provincial 48.1, and over-65s make up 31.8%. Foreign residents are 2.3%. Declared incomes, on the other hand, are above the provincial average.

Sardinia is the quietest region in Italy for earthquakes. Isili is in seismic zone 4, like 69 other municipalities in the province, with an expected acceleration of 0.050 g. In older houses the things to check are the roof, damp and the wiring and plumbing.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report works back from the address to the land parcel, with ground elevation and distances to services measured from the house.

Key points

  • Local centre of the Sarcidano, at around 500 metres.
  • Population down 14.0% since 2011; over-65s at 31.8%.
  • Seismic zone 4, the lowest in the national scale.

Overview

Isili is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 2,443 residents, ranked 33 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Isili 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 14.0%. 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 2.3% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Isili declared an average taxable income of 21,043 euros, above the provincial average (19,085 euros). The Italian average is 24,895 euros.

Isili is in climate zone D, with 1,741 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 523 metres above sea level.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 3.4% of the land in Isili, compared with 3.4% in the region. In 2024 built-up land grew by 0.9 hectares.

Radon and contaminated sites

Isili is not among the radon priority areas designated by the Regione Sardegna in 2022. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Isili: 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.

Land registry

The cadastral maps for Isili are public: from the address the report finds the sheet and parcel number.

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.
