Castel di Ieri, in the Subequana valley between L'Aquila and Sulmona

Castel di Ieri lies in the Valle Subequana, the stretch of inland Abruzzo along the Aterno river between the L'Aquila basin and the Peligna valley. The village sits just above five hundred metres, gathered on a rise with the valley fields below and mountains around. Sulmona and L'Aquila, both reachable by car, are the towns people rely on for services and work.

Much of the housing is stone houses in the old centre, often built against each other, plus more recent homes on the edges. In a block of joined houses, work on a neighbour's building can affect yours too, so before completing the purchase ask whether any structural work has been done or is planned on the building and on the block.

Earthquakes are the main issue. Castel di Ieri is in seismic zone 1, the highest class set by the Civil Protection Department, like 103 of the 108 municipalities in the province of L'Aquila, and expected ground acceleration in the village is about 0.260 g. For a masonry house, ask for the paperwork on any strengthening work and, if there is none, get a surveyor's or engineer's opinion.

There were 292 residents in 2023, down 11.2% from 329 in 2011. The estimated average age is 53.2, against 47.5 in the province, over-65s make up 34.9% and foreign residents 7.5%. Climate zone E means cold winters, and declared incomes are below the provincial average.

Revenue Agency cadastral maps are published, and the report links the address to the land parcel.
