Agosta, Aniene valley village near Subiaco

Agosta looks down on the Aniene valley from a rise above the river in the Subiaco area, on the eastern edge of the province of Rome. The landscape already belongs to the Simbruini mountains, with woods, steep slopes and hilltop villages, yet the capital stays within reach: the motorway to L'Aquila runs through the valley and takes you towards Rome in a time many commuters accept.

Buyers find stone houses in the old centre, with steps, alleys and access on foot, and newer homes along the roads running down towards the valley floor. For houses in the old village, the roof, damp and parking are what count; for those lower down, closeness to the river. The report checks the official flood and landslide maps for the exact address.

Istat, the national statistics office, counts 1,684 residents in 2023, down 4.3% from 1,760 in 2011. The average age is 47.0, against 46.0 in the province, and over-65s are 25.8%. Foreign residents make up 8.7% and households have 2.14 people on average. Declared incomes are below the provincial average.

Agosta is in seismic zone 2 under the Civil Protection classification, along with 96 other municipalities in the province, and the expected ground acceleration is 0.158 g. In a masonry building, ask whether work has been done on floors and roof and get the paperwork. The Revenue Agency publishes the cadastral maps and the report finds the parcel from the address.
