Chiauci, a hill village above the Trigno valley in Molise

From Chiauci the view drops towards the valley of the Trigno, the river that marks the border between Molise and Abruzzo for a long stretch. The village stands on a rise above eight hundred metres, in the province of Isernia, its stone houses gathered around the centre, with pastures, woods and fields all around.

This is a mountain municipality where travel matters: Isernia is the reference for jobs, secondary schools and hospital care, reached on provincial roads through the hills. People buying here often do so to return to a family village or for a summer house. Houses are mostly old, in stone masonry and on several floors; before making an offer, assess the roof, floors, damp and systems, plus the cost of heating them in climate zone E. The report reads the official landslide maps for the address, a check not to skip on the slopes.

The population has fallen sharply. Istat, the national statistics office, counted 198 residents in 2023, 70 fewer than the 268 of 2011, a fall of 26.1%. The estimated average age is 51.5, against 48.1 in the province of Isernia, and over-65s make up 33.8%. Declared incomes are below the provincial average.

In the province of Isernia, 32 municipalities are in seismic zone 1 and 20 in zone 2. Chiauci is in zone 2, with an expected ground acceleration in the village of about 0.233 g, still a high value. For a masonry house, ask for documents on any structural work and have a surveyor or engineer look at it. Revenue Agency cadastral maps are published.
