Gesico, a Trexenta village inland from Cagliari

The Trexenta, an area of low hills and open fields inland from Cagliari, is where Gesico lies. The centre sits at about 300 metres, with low houses grouped around the church and the main streets, and farmland all around. Cagliari remains the reference for hospital care, offices and many schools, while day-to-day shopping is done in the larger towns of the area.

The fall in residents is marked: there were 728 at the end of 2023, 158 fewer than in 2011, a drop of 17.8% (Istat, the national statistics office). The average age is 50.2 against 48.1 in the province, and over-65s make up 27.6%. Foreign residents account for 2.1%. Declared incomes are below the provincial average.

The typical home is the Sardinian village house, with an inner courtyard and, in older buildings, walls of stone or sun-dried earth brick. Buyers should look above all at damp in the walls, the state of the roof and the services; good insulation matters in summer, when the inland heat is strong, even more than in winter. This is climate zone D.

Earthquakes are not a significant issue. All 70 municipalities in the province are in seismic zone 4, the lowest class set by the Civil Protection Department, and the expected ground acceleration in Gesico is about 0.050 g.

The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report links the address to its land parcel. Along the streams that cross the countryside it is still worth checking the official flood maps, which the report reads for the exact spot.

Key points

  • Trexenta village in low hills inland from Cagliari.
  • 728 residents, down 17.8% since 2011.
  • Whole province in seismic zone 4, the lowest.
  • Courtyard houses: damp and roof are the first checks.

Overview

Gesico is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 728 residents, among the smallest in the province (63 of 70).

Earthquakes

For Italy's Civil Protection Department, Gesico 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 17.8%. The estimated average age is 50 years, higher than the province average (48). 28% of residents are over 65 (the regional figure is 27%). Foreign residents make up 2.1% of the population. On average, a household has 2.3 members.

In tax year 2024, taxpayers in Gesico declared an average taxable income of 14,734 euros, below the provincial average (19,085 euros). The Italian average is 24,895 euros.

Gesico is in climate zone D, with 1,416 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 300 metres above sea level.

Radon and contaminated sites

Gesico 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 Gesico: 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 Gesico are public: from the address the report finds the sheet and parcel number.

Liveability area by area
