Castelnuovo Don Bosco, the hills between Asti and Turin
The name comes from the saint: Giovanni Bosco, better known as Don Bosco, was born at the Becchi, a locality of Castelnuovo, and the Colle Don Bosco with its large basilica draws pilgrims from around the world. The town lies in the hills of the northern Asti province, towards the border with the province of Turin, and many residents look to Chieri and Turin for work rather than to Asti.
The territory mixes a compact old centre on a hill with hamlets and farmsteads spread among vineyards, hazelnut groves and woods. Buyers find brick village houses, newer detached homes and old farmhouses to restore. On the hills, check slope and ground stability on the official landslide maps; the report checks them for the address, along with the flood maps.
With 3,092 residents in 2023, Castelnuovo ranks number 8 by population among the 117 municipalities of the province of Asti, an area made up almost entirely of small villages. Since 2011 the population has fallen 5.2%. The average age is 47.9, the same as the province, over-65s are 26.3% and foreign residents 10.1%. Declared incomes are a little below the provincial average.
Earthquakes are not an issue: the municipality is in seismic zone 4, like 112 others in the province, and the expected ground acceleration is 0.042 g. In farmhouses, roofs, damp and the state of timber floors matter more.
The Revenue Agency's cadastral maps cover the municipality: the report traces the plot and adds the local price band and distances to services.

Overview
Castelnuovo Don Bosco is a municipality in the province of Asti, in Piemonte. At the end of 2023 it had 3,092 residents, among the most populous in the province (8 of 117).
Earthquakes
For Italy's Civil Protection Department, Castelnuovo Don Bosco is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (113 of 117) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.042 g, a low value: the level with a 10% probability of being exceeded in 50 years, on rock.
In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
