Guamaggiore, wheat-growing hills in the Trexenta

The Trexenta is an area of hills planted with wheat in southern Sardinia, with Senorbì as its main town, and Guamaggiore is one of its villages. The centre lies at around 200 metres in an open landscape of fields and pasture, and village life still turns on farming. For city jobs and many services, people look to Cagliari, which can be reached by car.

The climate is mild, zone C, with hot, dry summers. In village houses, often built round an inner courtyard, the thing to watch is damp: some traditional homes in the south of the island are built of ladiri, sun-dried earth bricks, which need breathable plaster and good protection from rain. For newer houses, insulation and shading from the sun matter.

The village is losing people: 894 in 2023, 14.9% fewer than the 1,050 of 2011, according to Istat, the national statistics institute. The estimated average age is 49.0 (provincial figure 48.1) and over-65s are 28.6%, against 25.7% in the province. Foreign residents are very few, 1.2%. Declared incomes are below the provincial average.

Earthquakes are a minor concern: all 70 municipalities in the province are in seismic zone 4, the lowest step of the Civil Protection classification, and the expected ground acceleration is about 0.050 g. Buyers can focus on the roof, services and the condition of the walls.

The Revenue Agency publishes the cadastral maps, and the report finds the land parcel from the address. Flooding along streams and landslides on slopes are checked address by address on the official maps.

Key points

  • Trexenta, wheat-growing hills in southern Sardinia.

Overview

Guamaggiore is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 894 residents, ranked 58 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Guamaggiore is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 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 14.9%. The estimated average age is 49 years, in line with the province. 29% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.2% of the population. On average, a household has 2.1 members.
