Mentana, the Via Nomentana and the hills north-east of Rome
Mentana is in the history books for the battle of 1867, when Garibaldi's volunteers marching on Rome were stopped by papal and French troops; a memorial to the fallen and a museum keep its memory. Today the municipality sits in the hills north-east of Rome along the Via Nomentana, with its old centre on a hilltop and the outlying villages of Castelchiodato and Casali. Part of its former territory became the separate municipality of Fonte Nuova.
It is commuter country. The Nomentana and the roads towards the Rome ring road lead into the city, with journey times that lengthen considerably at rush hour. In recent decades districts of small villas and low blocks have spread over the tuff hills, often with gardens and at prices below those of the capital.
Mentana is growing and getting younger. Istat, the national statistics office, recorded 22,605 residents in 2023, up 8.8% on 2011. The average age is 43.7 against 46.0 for the province, and over-65s make up 19.2% against 22.9%. Foreign residents account for 14.3%, more than the provincial average. Declared incomes are well below the metropolitan average, which Rome pulls upwards.
For earthquakes the town is in seismic zone 2, like 97 of the 121 municipalities in the province, with expected ground acceleration of about 0.128 g. For houses put up quickly during the years of expansion, check the design, the structural sign-off and planning compliance, including any amnesty applications (condoni).
On the hills, slopes, banks and ditches matter. The report measures elevation and slope at the address and checks the official landslide and flood maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the land parcel is found from the address.

Earthquakes
For Italy's Civil Protection Department, Mentana is in seismic zone 2, a zone where strong earthquakes are possible. The region uses a finer breakdown: here the classification is 2B. Most municipalities in the province (97 of 121) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.128 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
For anyone buying in Mentana, 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.

The estimated average age is 44 years, lower than the province average (46). 19% of residents are over 65 (the regional figure is 23%). Foreign residents make up 14.3% of the population.
