Allerona, hill village above the Paglia valley

The village of Allerona stands on a hill in the countryside around Orvieto, above the valley of the river Paglia, while part of the population lives lower down at Allerona Scalo, near the valley floor. The two feel different: up top, the stone houses and narrow streets of the old village; below, newer homes and easier access to the main roads. Orvieto is the reference town for services and trains, and the A1 motorway runs along the valley.

Much of the municipality is woodland, including part of the Selva di Meana, a large oak forest. Buyers looking for a country house find farmhouses and smallholdings, often needing renovation; check the access road, water supply and drainage. Near the Paglia the report checks the official flood maps, on the hills the landslide maps.

Istat, the national statistics office, counts 1,691 residents in 2023, down 9.0% from 1,859 in 2011. The average age of 48.6 is in line with the province of Terni (48.9), with over-65s at 28.7%. Foreign residents are 6.2%; declared incomes remain below the provincial average.

Allerona is in seismic zone 3 under the Civil Protection classification, along with 16 other municipalities in the province, while 12 are in zone 2 and 4 in zone 1. The expected ground acceleration is 0.144 g. In the stone houses of the old village, have the roof, floors and wall connections checked. The Revenue Agency publishes the cadastral maps and the report finds the parcel.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
