Selargius, Campidanese courtyard houses on Cagliari's doorstep

You pass from Cagliari into Selargius without noticing: the municipality is part of the city's urban belt, along with Quartu Sant'Elena, Monserrato and Quartucciu, on the Campidano plain only a few metres above sea level. The old centre keeps its Campidanese houses, built around an inner courtyard with walls of sun-dried earth bricks, and every year hosts the Antico sposalizio selargino, a wedding celebrated in traditional dress and ritual.

For a buyer, Selargius is above all a place to live while working in Cagliari. Since the 1970s, districts of low-rise blocks and terraced houses have grown around the old core, with wider streets and more parking than in the city. The courtyard houses in the centre are a different matter: often large, needing restoration, with earth walls that call for suitable techniques and materials. Before buying one, have it inspected by a surveyor who knows this kind of building.

There were 28,437 residents in 2023, almost unchanged since 2011 (down 0.9%), making up 5.3% of the population of the 70 municipalities in the province. The estimated average age of 47.5 is just below the province (48.1), over-65s are 24.6% and foreign residents only 1.9%. Average incomes are in line with the province. There are few bars and restaurants per resident, 2.60 per 1,000 against 5.25, a sign that people go into the city for an evening out.

Earthquakes are a minor concern here. All of Sardinia is in the lowest hazard class and Selargius is in seismic zone 4, with expected ground acceleration of about 0.050 g. Maintenance, insulation and damp matter more, especially in earth-built houses.

The land is flat and crossed by channels, and in heavy storms some streets can fill with water. The report checks the official flood hazard maps for the address.

Key points

  • Part of Cagliari's urban belt, on the Campidano plain.
  • Campidanese courtyard houses with earth-brick walls.
  • 28,437 residents, foreign residents at 1.9%.

Overview

Selargius is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 28,437 residents, the third most populous in the province.

Earthquakes

For Italy's Civil Protection Department, Selargius 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 number of residents is nearly unchanged. The estimated average age is 47 years, in line with the province. 25% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.9% of the population. On average, a household has 2.2 members.

Income and climate

In tax year 2024, taxpayers in Selargius declared an average taxable income of 24,754 euros, in line with the province (24,865 euros). The Italian average is 24,895 euros.

Selargius is in climate zone C, with 1,001 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 11 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Selargius has 19 schools and 9 pharmacies. The Overture Maps data also lists 15 grocery shops and supermarkets, 25 healthcare facilities, 31 sports facilities and 5 parks and green areas.

There are 0.7 schools per 1,000 residents, fewer than the province average (0.9).

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 16.5% of the land in Selargius, compared with 3.4% in the region. In 2024 built-up land grew by 4.7 hectares.

Radon and contaminated sites

Selargius is not among the radon priority areas designated by the Regione Sardegna in 2022. 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 Selargius: 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 Selargius 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. Here it is worked out at the centre of each of the 79 inhabited census areas in Selargius. Half of the residents live in areas scoring 82 or more.
