Castel di Casio, the hamlets of the high Bologna Apennines

High in the Apennines south of Bologna, in the Porretta area, Castel di Casio is a mountain municipality made up of many hamlets scattered among woods, meadows and ridges, with no big centre. The main village is small, and much of the population lives in the hamlets, some along the valley roads, others more isolated higher up. Bologna is about an hour away by road, and services are found around Porretta.

The housing market is typical of the mountains: stone houses to restore, holiday villas built during the post-war boom and flats in small buildings. Many properties are second homes of Bologna families, used mainly in summer. If you plan to live here all year, consider the distance to services, how roads are kept clear in winter and heating, in an area where snow is not unusual.

There were 3,322 residents in 2023, down 4.5% since 2011, and the municipality is among the least populated in the province (49 out of 55). The average age is 48.8 against 46.6 in the metropolitan area, and over-65s make up 28.1%. Foreign residents account for 8.1%. Average declared incomes are clearly below the Bologna average.

Castel di Casio is in seismic zone 3 of the Civil Protection classification, but with an expected acceleration that is high for that zone, about 0.191 g: in stone houses, ask about the state of the walls and roof. For a house on the slopes, the report checks the official landslide maps for the address, and during a viewing it is worth taking a calm look at walls and floors.
