Castel San Pietro Romano, the village above Palestrina
Above Palestrina, at over seven hundred metres in the Monti Prenestini, Castel San Pietro Romano looks down on the countryside east of Rome. This is where Pane, amore e fantasia (Bread, Love and Dreams), the film with Gina Lollobrigida and Vittorio De Sica, was shot, and the old centre still has the narrow streets and stone houses of that time. Palestrina, just below, has shops and services; Rome is within driving distance for work and offices.
The centre is small and steep, with little room for cars: for a house in the village, check where you can park and how materials and furniture will get in. Outside the centre there are detached houses and homes with gardens on the slopes. At this height winters are cold (climate zone E), and heating has to be budgeted for. On the slopes the report reads the official landslide maps for the address, together with the gradient.
The population is almost stable: 844 residents at the end of 2023, 11 fewer than in 2011, according to Istat, the national statistics office. The average age is 46.2, close to 46.0 for the province, and over-65s are 21.4%, fewer than the provincial 22.9%. Foreign residents are 6.3%. Average declared incomes are below the figure for the province of Rome.
Castel San Pietro Romano is in seismic zone 2 (zone 1 is the most hazardous), like 97 of the 121 municipalities in the province, with an expected ground acceleration of about 0.165 g. For stone houses in the village, ask whether any strengthening, roof replacement or work on the floors has been done.
Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality, and the report finds the land parcel from the address.

For anyone buying in Castel San Pietro 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.
