For example: Via Marittima 1, Frosinone.

Frosinone, capital of the Ciociaria

Frosinone stands on a hill overlooking the valley of the river Sacco in southern Lazio, along the main motorway and railway between Rome and Naples. It is the capital of the Ciociaria, an area made up of many medium-sized towns, and the city is divided between its historic upper town and newer districts spreading towards the valley.

One figure sums up the province well: Frosinone is the most populous of its 91 municipalities, yet it holds only 9.3% of the population. At the end of 2023 there were 43,305 residents, 7.2% fewer than at the 2011 census. The estimated average age, 46.9, and the share of over-65s, 25.5%, are almost identical to the provincial figures. Foreign residents make up 8.0%.

For seismic purposes the city is in zone 2, regional sub-zone 2B, like 59 municipalities in the province; another 30 are in zone 1, the highest class, and 2 are in zone 3. The expected ground acceleration in Frosinone's built-up area is about 0.159 g, a medium-high value. Anyone considering a flat should ask about the design date, whether the building has had a seismic assessment and what work has been carried out on it.

As the provincial capital, Frosinone has plenty of services for its size. Overture Maps data record 70 healthcare facilities (1.62 per 1,000 residents against 0.60 across the province), 58 sports facilities (1.34 against 0.74) and 47 schools (1.09 against 1.13). The Ministry of Health lists 13 pharmacies, 0.30 per 1,000 residents, below the provincial average of 0.39.

The land registry is not an issue: the Revenue Agency (Agenzia delle Entrate) maps are published, and the report identifies the plot from the address. Between the hilltop old town and the valley below, however, landslide and flood hazard and local prices change, so the report checks them at the precise location.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.159 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Frosinone, 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
