It was built in the early 18th century, according to sources in 1707, following the granting of the concession. It is located along the tributary of the Chiavona, the Ciaonela, near the locality of Grumale and took its name from the nickname of the Brazzale family, who were the owners at the time.
A mill registered to Iseppo Brazzale, in the valley of Rocca, was already dated in 1699 when the heirs of the late Iseppo Brazzale requested from the Serenissima the supplication (or permission) to build a mill “with a single wheel to grind straw for the use of the village, situated between the valleys and mountains of Calvene.”
It was used for the production of sorghum flour (corn) utilizing water that came directly from the streams running along the Val de Ciòda and Val Porca, which converged at the foot of the ridge of Rocca.
It played an important role during the partisan resistance, as it was used to secretly grind at night for the partisans, thus avoiding the bans imposed by the fascists.
