Santadi, inland Sulcis between caves and vineyards

Santadi is an inland village in the Sulcis area of south-west Sardinia, in a valley surrounded by hills covered in Mediterranean scrub. It is known for the Is Zuddas caves, visited by tourists and school groups, and for wine, in particular the Carignano del Sulcis from the village winery. The coast at Porto Pino and the southern Sulcis is not far.

Homes are mostly low masonry houses, often with a courtyard, in the tradition of inland Sardinian villages. Buyers should expect long journeys to the hospital and main offices, in Carbonia or Cagliari, and check the distance to schools and pharmacies, which the report measures from the address. The climate is mild (climate zone C).

The population has fallen 13.3% since 2011, to 3,094 residents in 2023. The average age is 50.9, similar to the province (50.6), and over-65s are 32.1%. Foreign residents are very few (0.5%). Declared incomes are below the provincial average.

Earthquakes are not a significant issue: the whole of Sardinia is in seismic zone 4, the lowest, and the expected ground acceleration here is 0.050 g. In older houses, roofs, damp and services matter more.

The municipality belongs to the province of Sulcis Iglesiente. The Revenue Agency publishes cadastral maps, and the report identifies the plot and checks landslide and flood hazard on the official maps.

Overview

Santadi is a municipality in the province of Sulcis Iglesiente, in Sardegna. At the end of 2023 it had 3,094 residents, ranked 11 of 24 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Santadi is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 24 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 13.3%. The estimated average age is 51 years, in line with the province. 32% of residents are over 65 (the regional figure is 27%). Foreign residents make up 0.5% of the population. On average, a household has 2.2 members.

In tax year 2024, taxpayers in Santadi declared an average taxable income of 16,797 euros, below the provincial average (19,085 euros). The Italian average is 24,895 euros.

Santadi is in climate zone C, with 1,119 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 135 metres above sea level.

How built-up it is

Radon and contaminated sites

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