Castel Giorgio, the Alfina plateau above Orvieto

Castel Giorgio stands on the Alfina plateau, north-west of Orvieto, an Umbrian village a short distance from Lake Bolsena, which lies further south in Lazio. The land is a farmed volcanic tableland of fields, pastures and woods, and Orvieto, with its station on the Rome to Florence line and its motorway junction, is the reference for services and connections.

The plateau rises above five hundred metres and the climate zone is E: winters are cold, with fog and the occasional snowfall, and heating costs more than people tend to expect in Umbria. Housing is mostly village homes, small villas and farmhouses in the countryside. If you are buying an isolated farmhouse, access, utility connections, well or mains water and distance to services all matter, and the report measures these from the exact address.

The population is elderly. According to Istat, Italy's national statistics office, there were 1,989 residents at the end of 2023, down 8.7% on 2011, with over-65s at 36.1% against 28.8% for the province of Terni. The average age is 52.0. Foreign residents make up 4.9%. Declared incomes are below the provincial average.

Castel Giorgio is in seismic zone 3, like 16 other municipalities in the province, with an expected ground acceleration in the built-up area of 0.144 g. For a stone farmhouse, ask whether the roof, floors and walls have been worked on.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report goes from the address to the building's land parcel.
