Vallarsa (Brandtal in Cimbrian and German) is a town in the province of Trento, located in the homonymous valley, built by the waters of the River Leno that insinuates itself between the mountain range of Carega and that of Pasubio. About the origins of the name, there are several theories, according to some, in fact, it derives from "valle arsa" (the burnt valley) or "valle sempre asciutta" (the always dry valley) or "parched" (from the large amount of wood burned to produce charcoal), while other historians attest that it derives from the Cimbrian "vallis arsium" (narrow valley).
It is a conglomeration of several villages, the oldest of which dates back to the XIII century when Giacomo Castelbarco favored the immigration of German settlers. In the XV century, under the rule of the Venetian Republic, the residents favored the same privileges already granted to them by Castelbarco.
During the First World War, the population was evacuated and the Austrian troops built here a fortress to control the borders.
