Colleretto Castelnuovo, in the Valle Sacra above Castellamonte

Between Castellamonte and the mountains of the Gran Paradiso, the Valle Sacra is a small side valley of the Canavese, in northern Piedmont, with villages spread over wooded slopes. Colleretto Castelnuovo is one of them, with houses divided between the main village and several hamlets at around six hundred metres. For services people go down to Castellamonte and Cuorgnè, and for work also towards Ivrea and the Turin area.

The population figures have an unusual profile. Istat, Italy's national statistics office, counted 331 residents in 2023, against 347 in 2011 (a fall of 4.6%), and foreign residents make up 25.4%. The estimated average age is 47.8, almost the same as the 47.4 of the province of Turin, and 28.4% of residents are over 65. Declared incomes are below the provincial average.

The market offers stone houses in the hamlets, often with land, and a few newer detached homes along the main roads. For buyers, the access roads (sometimes narrow and steep), the amount of sun, which differs from one side of the valley to the other, and the state of the roofs all matter. In climate zone F winters are long, so insulation and heating should be weighed before the price.

The municipality is in seismic zone 3 on the Civil Protection scale, like 271 of the 312 municipalities in the province of Turin, with an expected acceleration of about 0.049 g. With a stone house, ask whether the floors are original timber or have been rebuilt, and how they are tied into the walls.

On the slopes and along the valley streams, the report checks the official landslide and flood maps for the exact address, starting from the Revenue Agency's cadastral maps.
