Calasca-Castiglione, in the Valle Anzasca towards Monte Rosa

The Valle Anzasca leaves the floor of the Ossola valley and climbs along the Anza stream to Macugnaga, at the foot of the east face of Monte Rosa. Calasca-Castiglione lies in the lower part of the valley: the name joins two places, and the municipality includes several hamlets scattered over the slopes, among the woods.

Buying here means proper mountains without isolation: the Ossola valley floor, with the road to Domodossola and the Simplon Pass, is a short distance away. Houses are mostly stone buildings with stone-slab roofs, often old family homes. The climate is cold (climate zone F, the coldest band) and on the shaded side of the valley winter sunshine is brief: aspect and insulation matter a lot.

In 2023 Istat, the national statistics office, counted 600 residents, 81 fewer than in 2011 (down 11.9%). The average age is 51.4, against 49.0 in the province of Verbano-Cusio-Ossola, and over-65s make up 32.2% of residents. Declared incomes are lower than the provincial average.

The municipality is in seismic zone 3, like 27 other municipalities in the province, with an expected ground acceleration of around 0.072 g. In a stone house, before any work, have a surveyor check the walls, floors and roof.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, and the report finds the land parcel from the address. In a narrow valley with streams and steep slopes, landslides and debris flows vary from one hamlet to the next: the report checks them on the official maps for the exact location.
