Trevi, the olive-grove town above the Umbrian valley

You can see Trevi from a long way off, from the road and railway crossing the Valle Umbra between Foligno and Spoleto: a town of pale stone clinging to the hillside at around four hundred metres, surrounded by dense olive groves. Extra virgin olive oil is the product it is known for, and the olive trees come right up to the town walls.

For buyers the municipality falls into two parts. Above is the historic centre, with steep lanes and stone houses, often small and on several floors, where cars are left outside the walls. Below, on the plain, are the station on the Foligno to Rome line and valley hamlets such as Borgo Trevi, with detached houses, industrial units and farmland. Foligno is a quarter of an hour's drive, Perugia under an hour.

The population is slowly shrinking: 7,959 residents in 2023, 4.5% fewer than in 2011 according to Istat, the national statistics office. The estimated average age is 47.7, close to the 47.4 of the province of Perugia, and over-65s make up 27.1%. Foreign residents account for 8.9%. Declared incomes are below the provincial average.

Eastern Umbria is earthquake country, and Trevi is in seismic zone 1, the highest band in the Civil Protection classification, along with 13 other municipalities in the province. The expected ground acceleration in the built-up area is about 0.232 g. After the tremors of recent decades many buildings in the centre were strengthened with public funds: before buying, ask to see the paperwork for those works, find out whether they covered the whole building or only part of it, and whether the adjoining houses were treated together.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here, and the report finds the plot from the address. On the hill, slope and landslides matter; on the plain, ditches and canals. Both are checked for the individual address.

Key points

  • Historic centre on the hill; hamlets and station on the plain.
  • Seismic zone 1, expected acceleration about 0.232 g.
  • Population down 4.5% since 2011; over-65s at 27.1%.
  • Houses in the centre: ask for the strengthening works paperwork.

Overview

Trevi is a municipality in the province of Perugia, in Umbria. At the end of 2023 it had 7,959 residents, ranked 18 of 59 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Trevi is in seismic zone 1, the highest-risk zone, where very strong earthquakes are possible. Only 14 of 59 municipalities in the province are in zone 1.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.232 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Trevi, 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.

Population

Compared with the 2011 census, the resident population has fallen by 4.5%. The estimated average age is 48 years, in line with the province. 27% of residents are over 65 (the regional figure is 27%). Foreign residents make up 8.9% of the population. On average, a household has 2.4 members.

Trevi is in climate zone E, with 2,208 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 412 metres above sea level.

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 69 inhabited census areas in Trevi. Half of the residents live in areas scoring 59 or more.
