Sutri, a tufa-rock town on the Via Cassia and the Francigena
Sutri stands on a spur of tufa, the soft volcanic stone of this area, along the ancient Via Cassia in the southern part of the province of Viterbo, about fifty kilometres from Rome. At the foot of the town are the Roman amphitheatre carved straight out of the rock, Etruscan tombs cut into the cliff face and the church of the Madonna del Parto, also hollowed out of a cave. The area is a regional park, and the Via Francigena pilgrim route passes through the centre.
Being close to Rome shapes the housing market. Many residents commute along the Cassia by car, or by train from Capranica-Sutri station on the regional line between Rome and Viterbo. Besides the houses in the old centre, often small and on several levels, there are villas and country houses in the area between the lakes of Vico and Bracciano, with gardens and land. Declared incomes are above the provincial average.
The population is growing slightly: 6,738 residents in 2023, up 2.8% on 2011. The average age is 48.1, close to the province (47.5), over-65s make up 26.3% and foreign residents 9.8%. Households are small, 2.12 people on average.
Two seismic zones meet in this part of Lazio: on the Civil Protection department's map, 40 municipalities in the province are in zone 2 and 20 in zone 3, Sutri among them, with an expected ground acceleration of about 0.082 g. The hazard is moderate. In the old centre, built of tufa blocks, the state of the walls and damp matter, and many buildings have caves and cellars dug into the rock beneath them, which should be inspected before buying.
The tufa cliffs around the town can shed rock, and streams in the gorges rise after heavy rain. The report assesses these hazards for the address and, using the Revenue Agency (Agenzia delle Entrate) cadastral maps, traces the plot.
