The Attone Bridge and the customs

Along the course of the Brembo River, in the municipality of Ubiale Clanezzo, is the medieval Attone Bridge, built in stone with a single arch, which is an element of considerable architectural and environmental value. With its shoulders firmly anchored to the rocks of the banks, it crosses the Imagna stream at the point where it flows into the Brembo. For very long years the only access route to the Brembana Valley passed through here, and for this reason the bridge played a very important role in trade connections with the transalpine. From this valley, in fact, it was possible to reach Passo San Marco and then, through Valtellina, to reach the Grisons. Today, the medieval bridge remains isolated from the trade routes, which allows, thanks to the context in which it is set, its historical and cultural value to be enjoyed in full nature. It is accessed via a specially marked path that leads from the road in the locality of Castello, where the Rocca di Clanezzo fortress is located, down to the Brembo River via a small road that winds through the bush. The surrounding landscape certainly makes the place attractive, and its views allow one to admire the naturalness of this stretch of river and the stream that flows into it. The bridge has been maintained in good condition, as has the cobblestone road that runs along it, and is passable on foot or by bicycle. In the central part one can see the crenellated pillars that once supported the gates that closed the passage. Also testifying to the importance of the place is the presence of an ancient building known as a watchtower or customs house, where the janitor who controlled and collected the toll resided. This preserves a tower structure that probably formed the original core of the building, which was later joined by a wooden lodge building.
Structural configuration: The bridge has a single-arch stone structure. Door hinges that closed the passage can still be seen. Can be visited daily. Illuminated at night.
