Trivigliano, hill country in the Ciociaria near Fiuggi

Trivigliano is a village in the Ciociaria, the traditional name for the area around Frosinone, in the north of the province, on a rise between Fiuggi and the Sacco valley. The old centre is gathered at the top, the surrounding countryside slopes down towards Lake Canterno, a karst lake protected as a nature reserve, and woods cover the hillsides. Fiuggi and Alatri are close, and Frosinone and Rome are reached by car.

For buyers, the village offers stone houses in the centre and villas scattered across the hills, often with a garden or land. Some come here for a weekend home within manageable reach of Rome; anyone living here year-round will need a car for almost everything. Winters are cold at this height (climate zone E), and in older houses insulation and the boiler need checking.

Istat, the national statistics office, counts 1,611 residents in 2023, down 4.8% since 2011. The average age is 46.3, close to the provincial 46.8, and foreign residents make up 5.7%. Declared incomes are in line with the provincial average.

In the province of Frosinone, 30 municipalities are in seismic zone 1 and 59 in zone 2. Trivigliano is in zone 2, with an expected ground acceleration of 0.162 g. For a masonry building, ask whether strengthening work has been done, with the paperwork.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report works back from the address to the land parcel. In karst country, with slopes and hollows, gradient and the official landslide and flood maps are read for the individual address.

For anyone buying in Trivigliano, 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.
