 Geographically, the Brenta river valley is a typical valley of the southern rim of the Alps.The particularities of the territory are its limestone mountains crossed by the river Brenta, which confers a fertile floor and steep walls to the surrounding territory.The most plausible hypothesis about the origin of the name "Valstagna" is that the name derives from the Cymbrian, a Germanic dialect, such as many other toponyms in the area.
