Arcinazzo Romano, the upland plain between Subiaco and Fiuggi
The Arcinazzo uplands, above 800 metres, open out between Subiaco and Fiuggi, on the border between the Rome metropolitan area and the province of Frosinone. Arcinazzo Romano has its village on a rise and, on the plateau, the remains of the Emperor Trajan's villa, along with meadows, woods and areas of holiday homes. Rome is about an hour and a half away by road.
The property market here has two sides. On one hand, the village houses, lived in all year round; on the other, the second homes built on the plateau in the second half of the twentieth century, used in summer to escape the heat of Rome. Anyone buying one of these should check heating, insulation, utility connections and whether any extensions were authorised. Winters are cold, with frequent snow (climate zone E).
There were 1,222 residents in 2023, down 12.3% since 2011 according to Istat, the national statistics office. The population is older: average age 51.1 against 46.0 in the province, and over-65s at 30.5% against 22.9%. Foreign nationals account for 3.2%. The average declared income is below the metropolitan area average.
Arcinazzo Romano is in seismic zone 2, like 96 other municipalities in the province, and the expected ground acceleration in the built-up area is about 0.159 g. For the holiday homes on the plateau, often built decades ago, it is worth having the structure and roof checked.
The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality, and the report finds the land parcel from the address. On a limestone plateau surrounded by slopes, the report reads landslide and flood hazard on the official maps for each point.

Earthquakes

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 Arcinazzo Romano, 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.
