Triei, Ogliastra hills a short drive from the coast

On the first hills behind the coastal plain of Ogliastra, in eastern Sardinia, lies the small village of Triei. The sea is a few minutes away by car, yet the village feels like an inland community, with vegetable plots and countryside planted with vines and olives.

Buyers in Triei mostly find family houses, often with a courtyard, and land in the countryside. For many the appeal is being close to the coast without living in a resort. Tortolì and the port of Arbatax are the reference points for services and connections, Lanusei for the hospital. The climate is mild (zone C), with hot, dry summers, so shade and roof insulation matter as much as heating. Declared incomes are below the Ogliastra average.

In 2023 there were 1,056 residents, down 6.2% on 2011 according to Istat, the national statistics office. The average age is 48.6 against 47.9 in the province, and over-65s are 27.1%. Foreign nationals are just 0.9%.

All 23 municipalities in Ogliastra are in seismic zone 4, the lowest class in the classification drawn up by the Civil Protection Department, Italy's emergency agency, and here the expected ground acceleration in the built-up area is 0.050 g. For a village house, damp, the roof and the heating and electrics matter more.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report traces the address back to the plot, which is also useful for farmland. Between the hills and the streams running down to the plain, the official flood and landslide maps are read for the exact spot.

Earthquakes

For Italy's Civil Protection Department, Triei is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 23 municipalities in the province are in the same zone.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
