For example: Via Casilina 1, Ferentino.

Ferentino, ancient walls above the Sacco valley

The walls of huge stone blocks around Ferentino's old town are among the oldest in Lazio, and they make it clear straight away that this was a hilltop settlement, on a rise overlooking the Sacco valley. This is Ciociaria, the area around Frosinone, on the old Via Casilina between Frosinone and Anagni.

Below the hill, on the plain, a large industrial and retail zone has grown up in recent decades, served by the Ferentino junction on the A1 motorway. Frosinone is a few minutes' drive away and Rome is reached by motorway. Buyers choose between the old town, with ancient houses built against one another on steep streets, and the plain and outlying hamlets, which are easier for anyone who drives.

According to Istat, the national statistics office, there were 20,048 residents in 2023, 4.4% fewer than in 2011. The average age of 46.0 is slightly below the provincial figure, 23.6% of residents are over 65 and 6.6% are foreign nationals. Declared incomes are a little above the provincial average, and sports facilities, at 19, exceed the average per resident.

Ciociaria takes earthquakes seriously. The province has 30 municipalities in zone 1, mostly in its eastern part, and 59 in zone 2 of the national classification by the Civil Protection Department. Ferentino is in zone 2, with expected ground acceleration of about 0.154 g. In the old town, structural work often involves several owners, because the houses form continuous blocks, so find out beforehand whether the building or the whole block has already been strengthened, and what paperwork exists.

The Revenue Agency's cadastral maps are available and the report starts from the address to find the plot. On the hillside and along the valley ditches, landslide and flood hazard are checked on the official maps for the exact spot, since conditions change a lot between the upper town and the plain.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.154 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Ferentino, 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.
