Trezzini Mill

Highlight • Historical Site

The Trezzini mill, whose paddle wheels kept turning for centuries and driving heavy millstones, was discontinued after the Second World War.

At the beginning of the path, not far from the road, are the two waterfalls formed by the Pevereggia, which drops sharply from the Piana di Sessa and then plunges downstream into the waters of the Tresa River (which marks the border between Italy and the Mark Switzerland). The waterfalls are located exactly on the border between the municipalities of Sessa and Monteggio. There are two different jumps: further up, next to the jetties of the path, you can easily admire a very beautiful first waterfall.
The second one is much higher and narrower and lies deeper than the way. You can see it from the ruins of the Mulino Trezzini, taking care not to stray too far from the path: in fact, near the mill, a deep ravine opens up. In the local dialect, it is called "Luëra", the place where the wolves lived, so much so that it was dangerous and difficult to reach.
The water of the Pevereggia was used in the past to supply the mill, which stopped its operation after the Second World War.
