Subiaco, Benedictine monasteries in the upper Aniene valley

Saint Benedict left the deepest mark on Subiaco. On the rocks above the river Aniene stand the Sacro Speco, built around the cave where he lived as a hermit, and the monastery of Santa Scolastica, where the first printed books in Italy were produced in the fifteenth century. The old town winds up to the Rocca abbaziale, the abbots' castle, at around four hundred metres, and all around rise the Simbruini mountains, protected as a regional park.

Rome is about seventy kilometres away. There is no railway station, and the town is linked by the road that runs down the valley to the Rome to L'Aquila motorway, which matters if you plan to commute daily. The housing market splits between the medieval core, with tall, narrow stone houses that often have no lift or parking, and the newer districts lower down, which are easier to reach by car.

Subiaco is losing residents. In 2023 there were 8,524, 542 fewer than the 9,066 counted in 2011 by Istat, the national statistics office, a fall of 6.0%. The estimated average age is 48.4, against 46.0 for the province of Rome; over-65s make up 27.6% and households are small, 2.15 people on average. Foreign residents account for 7.8%. For its size the town is well served, because it acts as the centre for the valley villages: 11 schools and education sites and 61 bars and restaurants.

In the metropolitan area of Rome, 97 of the 121 municipalities are in seismic zone 2 of the Civil Protection classification, Subiaco among them; expected ground acceleration in the built-up area is about 0.159 g. In the old stone houses of the medieval town, which lean on one another, find out whether walls and roofs have been strengthened and whether the work also covered the adjoining buildings.

The report uses the Revenue Agency (Agenzia delle Entrate) cadastral maps, available for Subiaco, and checks landslide hazard on the slopes and flood hazard along the Aniene at the exact address.

Overview

Earthquakes

For Italy's Civil Protection Department, Subiaco is in seismic zone 2, a zone where strong earthquakes are possible. The region uses a finer breakdown: here the classification is 2B. Most municipalities in the province (97 of 121) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.159 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Subiaco, 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.

The estimated average age is 48 years, higher than the province average (46). 28% of residents are over 65 (the regional figure is 23%). Foreign residents make up 7.8% of the population.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 39 inhabited census areas in Subiaco. Half of the residents live in areas scoring 60 or more.
