Fontana Liri, above the Liri valley in Ciociaria
Fontana Liri, in the Liri river valley in the Ciociaria area of southern Lazio, is best known as the birthplace of Marcello Mastroianni. The territory mixes fields, woods and scattered houses, with a hilly part and a lower part towards the river. Frosinone and Sora are the reference towns for work and services, both within driving distance.
The housing market is typical of a small inland town: detached homes, village houses over several floors and a few small blocks of flats. The difference between high and low ground is real. On the hill the lanes are narrow and the buildings old; lower down the ground is flatter but closer to the water, and the official flood maps need checking address by address, which the report does automatically.
The population has been falling for years. Istat, the national statistics office, records 2,684 residents in 2023, down 10.3% since 2011, and an average age of 48.4, above the 46.8 of the province of Frosinone. Over-65s make up 29.2% and foreign residents 6.2%. Average declared incomes are slightly above the provincial figure.
The town is in seismic zone 2, like 58 other municipalities in the province, and the expected ground acceleration in the built-up area is 0.205 g. In the province 30 municipalities are in zone 1, so the subject deserves attention. For a stone or mixed masonry house, ask what work has been done on floors and load-bearing walls.
The Revenue Agency publishes the cadastral maps for Fontana Liri, and the report finds the land parcel from the address.

For anyone buying in Fontana Liri, 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.
