Proceno, a castle village on the Tuscan border
Proceno lies in the hills of upper Tuscia, right on the border between Lazio and Tuscany. The old village, gathered around its medieval castle, stands at around 420 metres and looks out over open countryside of fields, woods and scattered farmhouses. Viterbo, the provincial capital, is some way off; for many errands people rely on the nearer towns of the area.
Buyers here usually want a stone house in the village or a farmhouse in the countryside. In the first case, the questions are about damp, timber floors, wiring and plumbing and whether you can park nearby; in the second, road access, water supply, drainage and the state of the roofs. The area is in climate zone E, with cool winters.
The population is small and elderly. In 2023 there were 530 residents, down 12.4% on the 605 of 2011. The average age is 52.0, against 47.5 in the province of Viterbo, and over-65s make up 32.1% (25.9% in the province). Foreign residents are 13.8%. Declared incomes are below the provincial average.
Proceno is in seismic zone 2 on the Civil Protection department's national scale, like 40 of the 60 municipalities in the province, with an expected ground acceleration of about 0.141 g in the built-up area. In a historic building it is worth asking a surveyor to check how walls and floors are tied together.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Proceno too, so the report reaches the land parcel from the address. For a farmhouse with land this is especially useful to check boundaries and areas, and to look up landslide and flood hazard on the official maps.

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 Proceno, 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.
