Gagliano Aterno, a castle village in the Subequana valley

The medieval castle rising above the houses is the most recognisable feature of Gagliano Aterno, a village in the Subequana valley in the province of L'Aquila, at around six hundred and fifty metres. Around it are fields, pastures and mountains, and the roads lead one way towards L'Aquila and the other towards the Sulmona basin, the two places people rely on for hospital, secondary schools and work.

The old centre is compact, with stone houses built against one another. For a buyer, the structure comes first. Gagliano Aterno is in seismic zone 1 on the scale set by the Civil Protection Department, like 103 of the 108 municipalities in the province, with a high expected ground acceleration of about 0.261 g in the built-up area. Before making an offer, ask whether the building has had repair or seismic improvement work, get the paperwork, and in a row of attached houses find out whether the work covered the whole block or only part of it.

Istat, Italy's national statistics office, counted 225 residents in 2023, against 255 in 2011: 30 fewer, a fall of 11.8%. The estimated average age is 51.4, against 47.5 in the province, and over-65s make up 34.7%. Foreign residents account for 14.7%. Declared incomes are slightly below the provincial average.

This is climate zone E, with cold winters, though shorter than on the higher mountains. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report links the address to its land parcel, checks the official landslide and flood maps and measures the distance to the pharmacy, schools and shops.
