The bridge was built in 1378 under the authorization of the Marquis of Monferrato.
It replaced a wooden bridge that was frequently destroyed by the turbulent waters of the Stura.
The 37-meter height was designed to prevent the river's spring floods from damaging the stone arch.
The structure is built entirely of dry-stone masonry without the use of mortar between the primary stones.
In 1999, the site was officially declared a protected natural area by the Piedmont Region.
The Ponte del Diavolo, or Devil’s Bridge, is a historic stone bridge built in 1378 that spans the Stura di Lanzo river in Lanzo Torinese, Italy. The structure features a single 37-meter high arch spanning the narrow, rocky gorge of the Rocciamelone torrent. Constructed to improve trade routes between Lanzo and Turin, the bridge is composed of local gneiss and serpentine stones. It was commissioned by the town of Lanzo to replace a previous crossing and was financed through a wine production tax. The bridge remains a notable example of late-medieval civil engineering in the Piedmont region. Its elevated position offers a view of the river passage between the high, vertical canyon walls. The site is a protected area, part of the Parco del Ponte del Diavolo, which includes surrounding trails for hikers.
The viewpoint located on the higher trail path, providing a profile shot of the bridge arch against the gorge walls.
Wear sturdy, closed-toe hiking shoes as the paths leading down to the river are uneven and rocky.
Visit during the shoulder seasons to avoid the heat of the canyon and potential summer overcrowding.
Avoid approaching the river edge during periods of heavy rainfall, as the canyon is prone to sudden water level changes.
Respect the natural surroundings by staying on marked trails and carrying out all waste.
