Tergu, a Romanesque church inland from Castelsardo

Inland from Castelsardo, with the Gulf of Asinara a short way off, Tergu is a country village in the Anglona area of northern Sardinia. The houses are gathered on a rise at around three hundred metres, and around the centre lies open land made up of smallholdings, unsurfaced roads and scattered homes.

Outside Sardinia the name is known for the Romanesque church of Nostra Signora di Tergu, built by Benedictine monks in the Middle Ages, with the ruins of their monastery beside it. Otherwise Tergu is a quiet residential place where a car is part of daily life: secondary schools, hospitals and larger shops are in Castelsardo or Sassari.

Istat, the national statistics office, counted 608 residents in 2023, 6 fewer than the 614 recorded in the 2011 census, a fall of 1.0%. The average age is 48.2, against 48.3 across the province of Sassari, and over-65s make up 28.0% of residents. Households average 2.04 people, and declared incomes are below the provincial average.

Earthquakes are a minor concern here. All 66 municipalities in the province, Tergu included, are in seismic zone 4, the lowest class, and the expected ground acceleration in the built-up area is around 0.050 g. In a country house or an old stone building, damp walls, the roof and the state of the wiring and plumbing matter more.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the municipality, so the report can trace an address to its land parcel. For an isolated rural property it is also worth checking access, the distance to services and the official flood maps along watercourses, which the report reads at the exact location.

Key points

  • Anglona village known for the Romanesque church of Nostra Signora di Tergu.

Overview

Tergu is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 608 residents, ranked 50 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Tergu 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 number of residents is nearly unchanged. The estimated average age is 48 years, in line with the province. 28% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.0% of the population. On average, a household has 2.0 members.

Income and climate

In tax year 2024, taxpayers in Tergu declared an average taxable income of 16,193 euros, below the provincial average (21,361 euros). The Italian average is 24,895 euros.

Tergu is in climate zone D, with 1,452 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 284 metres above sea level.

The data shows no grocery shops and supermarkets within the municipality, against a provincial average of 0.7 per 1,000 residents.

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

Radon and contaminated sites

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

Liveability area by area
