Arrone, the clifftop village in the Valnerina

Arrone is one of the villages of the Valnerina near Terni: the old core sits on a rock above the river Nera, with its houses packed tightly together, and below it spreads the newer part of the village, along the road that follows the valley. Terni is about twenty minutes away, and the drive passes close to the Marmore Falls; Lake Piediluco is not far off.

The housing market splits three ways: the old village, with stone buildings that are often small and without nearby parking; the valley floor, with more practical houses and small blocks of flats; and the countryside and hamlets on the slopes, with farmhouses and homes with land. Part of the demand comes from second-home buyers drawn by the river and the footpaths. Declared incomes are below the provincial average.

The population is falling: Istat, the national statistics office, counts 2,526 residents in 2023, down 11.0% on 2011. The average age is 49.2, almost the same as the 48.9 of the province of Terni; 29.3% are over 65 and 10.1% are foreign residents.

Earthquakes are the first issue to consider. Arrone is in seismic zone 1, the most hazardous class under the Civil Protection classification, which it shares with just 3 other municipalities in the province, and the expected ground acceleration in the built-up area is 0.195 g. For a house in the old village, always ask what structural work has been done and under which permits.

The Revenue Agency (Agenzia delle Entrate) cadastre is published. Between the rock, the slopes and the banks of the Nera, the report checks the official landslide and flood maps for the address.

For anyone buying in Arrone, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
