The route start from the hills of Belveglio from which we proceed southwards for
about 7 km and going up in altitude we arrive in the territories of Vinchio, altitude
261 m., famous for the production of wine and for many events connected to it. The
village is of considerable importance as it is the intersection of three streets of
Roman origin (Ramaudio, Luparia and Fonsmagna). The predominantly hilly area is
famous for the cultivation of both white and red grapes. The natural area of Val
Sarmassa is also of considerable importance. The area contains paleontological and
naturalistic features typical of the Asti area. The place has a lot of importance
from the landscape and historical-literary point of view too: in fact, in these areas
many of the stories told by Davide Lajolo, a well-known journalist and writer born in
Vinchio, are set. You then cross the territory of Vinchio, whose first historical
evidence dates back to 948 AD, to then continue towards Noche for about 3.5 km. From
the hamlet of Noche it is possible to walk along the 3A path variant that leads to
San Marzano Oliveto. The stage then goes towards its conclusion continuing for about
6.5 km arriving in the historical center of Castelnuovo Calcea. The name derives from
the name 'Castrum Novum' (new camp), while Calcea da 'ad calcarias' (topped up road),
which could have been the Roman road that often required reinforcement works. After
the Gauls and the Celts on the lands where Castelnuovo rises, the Lombards and the
Franks dominated. Before being ceded to the House of Savoia in 1735, it was part of
the Duchy of Milan. The village rises in a panoramic position, from where you can
admire the countless hills cultivated with vineyards that supply some of the most
renowned wines of the territory: Barbera, Grignolino, Cortese and Dolcetto.
