Civitella d'Agliano, the Teverina hills above the Tiber
Civitella d'Agliano is a village in the Teverina, the band of hills in the province of Viterbo that runs down to the Tiber valley on the border with Umbria. The old village stands on a spur of tuff, the soft volcanic rock of this area, and around it the landscape mixes vineyards, olive groves and the eroded clay gullies (calanchi) typical of this part of Lazio.
Buyers usually choose between a house in the village, with thick walls, stairs and sometimes cramped rooms, or a farmhouse in the countryside, often with land. Either way the structure and roof deserve a careful check, and for farmhouses also water supply, drainage and access roads. Viterbo and Orvieto are the main towns nearby.
Istat, the national statistics office, counts 1,450 residents in 2023, down 12.5% since 2011. The population is older: average age 49.9 against 47.5 for the province, with over-65s at 33.3%. Foreign residents make up 9.4%. Declared incomes are below the provincial average.
The municipality is in seismic zone 2, like 39 other municipalities in the province of Viterbo, with an expected ground acceleration of 0.145 g. For buildings on tuff, find out whether there has been any consolidation work and what the ground beneath the foundations is like.
On the spurs and gullied slopes the report checks the official landslide maps for the address; on the valley floor towards the Tiber, the flood maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report reaches the land parcel.
