Bonnanaro, the Meilogu and the prehistoric culture named after it

Archaeologists know Bonnanaro for the prehistoric culture named after it, based on finds made in the village's territory and spread across Sardinia at the start of the Bronze Age. Today Bonnanaro is a small village in the Meilogu, the hill country inland from Sassari, among fields, pasture and uplands, not far from the SS131 Carlo Felice highway.

Its position on the island's main road axis helps: Sassari is a reasonable drive away. The village has basic services; for anything else you go to nearby towns or into the city. Houses in the centre are stone, often several storeys high and set side by side along the streets, with inner courtyards; some need renovating. The climate is that of the hills, with mild but damp winters (climate zone D).

The population is shrinking and ageing. In 2023 there were 910 residents, 10.9% fewer than in 2011 according to Istat, the national statistics office; the average age is 50.5 against 48.3 for the province, and over-65s make up 33.1% against 26.6%. Households average 2.00 people, foreign residents account for 1.8%, and declared incomes are below the provincial figure.

Earthquakes are not a significant concern: all 66 municipalities in the province of Sassari are in seismic zone 4 under the Civil Protection classification, and in Bonnanaro the expected ground acceleration is 0.050 g. In stone houses, damp walls, roofs and the plumbing and electrics matter most.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, so the report goes from the house number to the land parcel. Landslide hazard on slopes and flood hazard along watercourses are read for the individual address.

Overview

Bonnanaro is a municipality in the province of Sassari, in Sardegna. At the end of 2023 it had 910 residents, ranked 36 of 66 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Bonnanaro 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 10.9%. The estimated average age is 50 years, higher than the province average (48). 33% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.8% of the population. On average, a household has 2.0 members.

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 Bonnanaro. Half of the residents live in areas scoring 74 or more.
