Supino, on the Lepini mountains above the Sacco valley

Supino's old town clings to the side of the Lepini mountains facing the Sacco valley, above Frosinone and Ferentino. A few minutes' drive takes you down to the valley floor, where you find the A1 motorway, the Rome to Cassino railway with the Ferentino-Supino station, and the industrial areas of Ciociaria, the traditional name for this part of southern Lazio.

The municipality has two sides. Up top is the old village, with stone houses packed together, steep streets and little room for cars. Further down, towards the valley, newer detached houses and small apartment blocks have spread out, handier for people working in Frosinone or commuting to Rome. Slope, access and prices all change between the two.

In 2023 Supino had 4,600 residents, down 6.0% on 2011. The average age is 46.5, almost the same as the province (46.8), over-65s make up 24.5% and foreign residents 9.0%. Declared incomes are slightly below the provincial average.

The province of Frosinone has significant earthquake hazard: 30 municipalities are in zone 1 and 59 in zone 2 of the Civil Protection classification, including Supino, where the expected ground acceleration in the built-up area is about 0.141 g. For an old-town house, ask whether the walls and floors have been strengthened; for a newer block, ask for the design year and whether it meets seismic standards. The limestone slopes of the Lepini above the town are steep and in places prone to rockfall or landslides. The report checks the official maps for the address.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.141 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Supino, 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.
