Casalvieri, hills of the Val di Comino
Casalvieri is a hill village in the Val di Comino, the green basin in the province of Frosinone closed off to the east by the mountains that separate it from Abruzzo. The municipality has a compact centre and many hamlets scattered across the slopes among olive groves, woods and vegetable plots, and it has a long history of emigration: many families have relatives abroad who come back in summer.
This shows in the housing market. Alongside people who live here all year there are emigrant families who return for the holidays, and houses passed down to heirs. Buyers can find plenty of space at low prices, but should check the condition of the building and that the paperwork is in order. Sora and Cassino are the larger towns for work, the hospital and secondary schools, both reachable only by car.
According to Istat, the national statistics institute, there were 2,422 residents in 2023, down 15.5% on 2011. The average age is 48.3 against 46.8 in the province of Frosinone, over-65s make up 27.3% and foreign residents 5.8%. Declared incomes are below the provincial average.
The Val di Comino is one of the most earthquake-prone parts of Lazio. Casalvieri is in seismic zone 1, like 29 other municipalities in the province, with an expected acceleration of 0.251 g, a high value. Before buying, have a surveyor examine the structure and ask what seismic strengthening has been carried out.
The report measures elevation and gradient at the address, checks the official hazard maps for the slopes and uses the Revenue Agency (Agenzia delle Entrate) cadastral maps to identify the land parcel.
