Graffignano, the Tiber valley and its tuff castles

Graffignano overlooks the Tiber valley from the Tuscia side, the area around Viterbo, on a tuff outcrop above the river. The village has its own castle, and the hamlet of Sipicciano has a second one, a reminder that these heights once watched over the valley. Around them are olive groves, woods and fields, with the Tiber plain lower down.

For a buyer, distance to the main towns is what counts: Viterbo is the provincial capital, and for roads and trains towards Rome you head down into the valley. Houses in the old village are tuff-built, often on several levels with cellars dug into the rock; outside the centre there are detached houses and farmhouses. Near the river the official flood maps should be checked for the address, which the report does for every plot.

According to Istat, the national statistics office, there were 2,090 residents in 2023, down 9.9% on 2011. The average age is 49.6, above the 47.5 of the province of Viterbo, and over-65s make up 29.8%. Foreign residents account for 4.7%. Declared incomes are below the provincial average.

The municipality is in seismic zone 2, with an expected ground acceleration of 0.144 g. In tuff houses, have damp, floors and cellars checked, and ask whether any strengthening work has been done.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps: the report traces the plot and adds the official landslide maps, useful at the edges of the cliffs. The climate zone is D.
