Etymology

The name Strona comes from storn or strom, celtic roots for "flowing waters" or "river".^[4] Postua is a comune located in the valley formed by the Strona.

Geography

The Strona di Postua starts in the Biellese Alps with two branches which meet at Alpe Aigra. It then flows from NW to SE reaching the village of Roncole and the inhabited part of its valley. After flanking Postua and Guardabosone it enters into the Valsessera and flows into the river Sessera near Crevacuore.^[1]

The old Postua stone bridge across the Strona.
