Tessennano, Tuscia farmland between Canino and Tuscania

In western Tuscia, between Canino and Tuscania, the countryside is a mix of farmed plateaus, olive groves and ravines cut by streams, and Tessennano is a small village in the middle of it. Lake Bolsena lies to the north, the coast at Montalto di Castro to the west, and Viterbo is a drive away. For work, many people look to Viterbo or to local farming.

Village houses are mostly tuff stone and masonry, with farmhouses scattered across the fields. Tuff, the soft volcanic stone of this area, is a good building material but it soaks up moisture, so in an older house check walls against the ground, cellars and floors. Climate zone D means moderate winters, with heating cheaper than in the mountains.

In 2023 Tessennano had 288 residents, 62 fewer than the 350 of 2011, a fall of 17.7%. The estimated average age is 53.4 against 47.5 in the province of Viterbo, over-65s make up 35.1% and foreign residents 8.0%. Declared incomes are below the provincial average.

The municipality is in seismic zone 2, like 40 of the 60 municipalities in the province, and expected ground acceleration in the village is about 0.138 g. For a masonry house, ask about any structural work and check how well walls and floors are tied together.

Revenue Agency cadastral maps are published, which helps with farmhouses that come with several plots of land, and the report goes from the address to the land parcel.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.138 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Tessennano, 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.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection.
