Semestene, a Meilogu village and the church of San Nicola di Trullas

In the countryside around Semestene, among pastures and dry-stone walls, stands the Romanesque church of San Nicola di Trullas, one of the small medieval monuments of northern Sardinia. The village lies in the Meilogu, an area of plateaus and hills inland in the province of Sassari, at around three hundred and eighty metres. Sassari and Oristano are reached via the Carlo Felice highway, the road that runs the length of the island.

This is farming and grazing country, with low houses and courtyards. Buyers here are often after a family house or a base in the countryside. The checks are those for any old house: the roof, damp, wiring and plumbing, and the real distance to services, which the report calculates from the address.

Residents are few and mostly elderly. In 2023 Istat, Italy's national statistics office, counted 125, down 26.9% on the 171 of 2011. The estimated average age is 58.3, against 48.3 for the province, and over-65s make up 44.8%. Declared incomes are below the provincial average.

Earthquake risk is low across the island. All 66 municipalities in the province of Sassari are in zone 4, the lowest on the Civil Protection Department's scale, and the expected ground acceleration here is about 0.050 g. In stone houses, upkeep is what to look at most.

For landslides and flooding the report reads the official maps at the individual address. The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Semestene, so the plot can be found starting from the house.

Overview

Semestene is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 125 residents, among the smallest in the province (65 of 66).

Earthquakes

For Italy's Civil Protection Department, Semestene 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 26.9%. The estimated average age is 58 years, higher than the province average (48). 45% of residents are over 65 (the regional figure is 27%). Foreign residents make up 6.4% of the population. On average, a household has 1.6 members.

Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslide and flood hazard changes from one street to the next even within Semestene: 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.

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.
