Thiesi, the Meilogu plateau and sheep's milk

Thiesi stands on a plateau in the Meilogu area of inland Sassari province, at around 450 metres, among pasture, dry-stone walls and open fields. It is a village with a shepherding tradition, known across Sardinia for processing sheep's milk and making cheese, work that still employs some of its residents. The centre has stone houses and regular streets, with newer neighbourhoods at the edges.

For buyers, Thiesi is a village with everyday services and a market of detached houses at moderate prices. Sassari is the reference for the university, the hospital and public offices, reached by car along inland roads. Winters are cooler than on the coast, climate zone D, so check insulation and heating in stone houses.

According to Istat, Italy's national statistics office, there are 2,715 residents (2023), down 9.7% since 2011. The average age is 49.5, against 48.3 in the province, and 30.6% of residents are over 65. Foreign nationals make up 3.7%. Declared incomes are in line with the provincial average.

All 66 municipalities in the province of Sassari are in seismic zone 4, the lowest, with an expected ground acceleration of 0.050 g. Earthquakes are a minor issue here; for older houses, roofs, damp and services matter more.

The report starts from the address and measures real distances to schools, pharmacies and shops, useful in a village where many services are in the centre. It also checks the official landslide and flood maps.

Key points

  • Meilogu plateau at around 450 metres, inland Sassari province
  • 2,715 residents, down 9.7% since 2011

Overview

Thiesi is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 2,715 residents, ranked 19 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Thiesi 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.
