Terelle, on the slopes of Monte Cairo above Cassino

Terelle is a mountain village on the slopes of Monte Cairo, at around nine hundred metres, above the Cassino plain. The road up from the valley is long and winding, and that shapes everyday life: for work, schools and hospital care people go down to Cassino, which also has a station on the Rome to Naples line.

The population has dropped markedly: 285 residents in 2023 against 460 in 2011, 175 fewer and a fall of 38.0%. It is an old village, with an estimated average age of 56.0 (provincial figure for Frosinone 46.8) and over-65s at 42.8%, against 25.4% across the province. Foreign residents make up 0.7%, and declared incomes are well below the provincial average.

People buying in Terelle are usually after a family home or a cool summer retreat. Houses are mostly masonry, built in several stages. In climate zone E, at this height, winters are cold and can bring snow, so check the heating, insulation and roof, along with access in the hardest months.

For earthquakes, the municipality is in seismic zone 1, the highest class, like 30 of the 91 municipalities in the province, with expected ground acceleration of about 0.242 g. Before buying a masonry house, ask for the paperwork on structural work and have a surveyor or engineer look at it. On the slopes, the report also checks the official landslide maps for the address.

Revenue Agency cadastral maps are published.
