Filettino, the source of the Aniene and the Simbruini Mountains

Filettino lies above a thousand metres in the upper Aniene valley, inside the Simbruini Mountains regional park: the springs of the river that later flows past Subiaco and Tivoli on its way to Rome rise on its land. The village has stone houses packed on the slope, beech woods all around and, higher up, the Campo Staffi ski area.

The market is shaped by mountain tourism: alongside residents' homes there are many second homes, used at winter weekends and in summer. If you are thinking of living here all year, consider climate zone F (the coldest), snow, mountain roads and the distance to hospital and secondary schools, which are in the larger towns down the valley.

In 2023 there were 535 residents, down 2.9% from 551 in 2011. Households are small, 1.61 people on average, and over-65s make up 27.9%. The average age is 50.4 against 46.8 in the province of Frosinone. Declared incomes are below the provincial average.

Filettino is in seismic zone 2, together with 58 other municipalities in the province, and the expected ground acceleration in the village is about 0.179 g. For a stone house in the centre, ask whether strengthening work has been carried out and ask to see the building permits.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps and the report traces the address to its parcel. High in the mountains, slopes and landslides change from one spot to the next, and the report checks them on the official maps for the plot.

Earthquakes

For Italy's Civil Protection Department, Filettino is in seismic zone 2, a zone where strong earthquakes are possible. The region uses a finer breakdown: here the classification is 2B. Most municipalities in the province (59 of 91) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.179 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Filettino, 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.
