Capranica, a tufa-ridge village between Sutri and the Cimini hills

In Tuscia, the southern part of the province of Viterbo, Capranica lies between Sutri and Vetralla on the edge of the Cimini hills. The historic centre is built on a long, narrow spur of tufa, the local volcanic stone, with sheer sides dropping into wooded gorges, a shape typical of villages in this volcanic area. The newer districts have grown up outside the old village, on the plateau.

For anyone working in Rome, the railway is the big advantage: Capranica-Sutri station is on the regional Rome-Viterbo line, so the capital can be reached by train without facing the traffic on the Via Cassia. Viterbo is about twenty kilometres away. Buyers choose between a house in the old village, with alleys, steps and little parking, and the detached houses on the plateau, easier for families.

There were 6,354 residents at the end of 2023 according to Istat, the national statistics office, down 4.4% on 2011. The average age is 46.8, slightly below the province, and foreign residents make up 10.9%. Declared incomes are just below the Viterbo average.

In the province of Viterbo, 40 municipalities are in seismic zone 2 and 20 in zone 3 on the Civil Protection scale. Capranica is in zone 3, with an expected ground acceleration of about 0.092 g. In the old village the tufa buildings are ancient and often built against one another: before completion, have a surveyor look at the walls and floors.

Tufa cliffs can crumble and the gorges collect storm water, so for houses on the edge of the spur the report checks the landslide maps at the exact spot. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report goes from the address to the land parcel.

Key points

  • Village on a tufa spur, with a station on the Rome-Viterbo line.

Earthquakes

For Italy's Civil Protection Department, Capranica is in seismic zone 3, a zone where strong earthquakes are possible but rare. The region uses a finer breakdown: here the classification is 3A. Only 20 of 60 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.092 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
