Vallerano, a tufa village among Cimini hazel groves

On the slopes of the Cimini hills, in the Tuscia area south-east of Viterbo, Vallerano sits on a spur of tufa, the soft volcanic stone of the region, surrounded by hazelnut orchards and chestnut woods. Hazelnuts provide work for much of the area, and the landscape shows it: dense rows of trees, country lanes and scattered farmhouses.

The old centre is compact, with tall narrow houses built on the tufa, sloping alleys and little room for cars. Buying there means stairs, cellars cut into the rock and renovation work that is often substantial. Outside the historic core there are more recent homes with gardens and parking. For work and larger services people look to Viterbo, reachable by car.

Istat, the national statistics office, records 2,397 residents in 2023, down 8.3% since 2011. The average age is 48.8, a little above the provincial 47.5, and over-65s make up 27.7%. Foreign residents account for 7.1%.

The province of Viterbo spans two seismic zones, and Vallerano is in zone 3, together with 19 other municipalities. The expected ground acceleration in the village is 0.107 g. In the tufa houses of the centre, have a surveyor look at cracks, timber floors and the condition of any vaults.

The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality. The report uses them to reach the land parcel and checks the official landslide maps for that address, which is useful for houses on the edge of the spur.

Earthquakes

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