Trevico, above a thousand metres in eastern Irpinia

Trevico sits on top of a hill in eastern Irpinia, above 1,000 metres, with views over the hills and valleys towards Puglia. The film director Ettore Scola was born here. The climate is that of the Apennine mountains: climate zone F, long cold winters.

The village has lost many of its people. Istat, the national statistics office, counted 826 residents at the end of 2023, 246 fewer than in 2011, a fall of 22.9%. The average age is 51.1, against 46.2 in the province of Avellino, and over-65s are 31.8%, against 23.9%. Declared average income is below the provincial figure.

For buyers the main issue is earthquakes. Trevico is in seismic zone 1, the highest in the Civil Protection classification, like 57 other municipalities in Irpinia, and the expected ground acceleration in the built-up area is about 0.249 g. Much of Irpinia was rebuilt after 1980: find out whether a house was rebuilt or strengthened in those years, ask for the plans and sign-offs, and have an engineer look at it before making an offer.

Beyond that, roof upkeep, insulation and heating matter more at this height than elsewhere, as does the access road in snow and ice.

The Revenue Agency (Agenzia delle Entrate) cadastre is published and the report links the address to its land parcel. On the slopes around the village, gradient and landslides are read on the official maps for the exact plot.

For anyone buying in Trevico, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.

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.
