Siligo, Maria Carta's village in the Logudoro

Siligo is the birthplace of Maria Carta, the singer who made traditional Sardinian song known far beyond the island. It lies in the Logudoro, in northern Sardinia, at around 420 metres, in a landscape of hills, plateaus and open farmland; Sassari is the reference point for work, hospital care and offices, and is reached by car.

The housing market is that of a small, ageing village: many family homes of stone or concrete block, often on two floors. Before buying, check the roof, walls, wiring and plumbing, and whether the house matches its cadastral floor plans. In climate zone D winters are mild, but damp is common in houses left closed.

The figures show a village that is emptying and ageing. At the end of 2023 there were 765 residents, down 16.1% on 2011. Over-65s make up 36.7%, against 26.6% in the province of Sassari, and the average age is 51.8 (provincial figure 48.3). Foreign residents account for 3.3%. Average incomes are below provincial levels.

Earthquakes carry little weight in the decision: all 66 municipalities in the province of Sassari are in seismic zone 4, the lowest, and here the expected ground acceleration is about 0.050 g. In old houses, maintenance deserves more attention than the structure.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, and the report goes from the address to the land parcel. On slopes and along watercourses, the official landslide and flood maps are read for the precise location of the house.

Key points

  • Birthplace of the singer Maria Carta, in the Logudoro.

Overview

Siligo is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 765 residents, ranked 42 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Siligo is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 66 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 16.1%. The estimated average age is 52 years, higher than the province average (48). 37% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.3% of the population. On average, a household has 1.9 members.

In tax year 2024, taxpayers in Siligo declared an average taxable income of 19,554 euros, below the provincial average (21,361 euros). The Italian average is 24,895 euros.

Siligo is in climate zone D, with 1,835 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 424 metres above sea level.

How built-up it is

Radon and contaminated sites

Siligo is one of the municipalities designated as a radon priority area by the Regione Sardegna in 2022. According to the ISPRA map, the estimated radon emission in the municipality is medium. 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 Siligo: 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 Siligo 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 6 inhabited census areas in Siligo. Half of the residents live in areas scoring 72 or more.
