Riserva naturale del Ponte del Diavolo, Regional nature reserve in Metropolitan City of Turin, Italy.

The Riserva naturale del Ponte del Diavolo is a regional nature reserve in the municipality of Lanzo Torinese, Metropolitan City of Turin, protecting the gorge of the Stura di Lanzo stream. Its name comes from the stone bridge, called Pont dël Ròch in Piedmontese, that crosses the ravine. Behind the Chapel of San Rocco, at the Lanzo end of the bridge, the rocks show the potholes known as the Marmitte dei Giganti.

The Gothic arch was built in 1378 using funds raised from a wine tax collected over a decade. The nature reserve itself was formally established in 1993 under regional law.

The reserve takes its name from the medieval arch that spans the gorge, which served as a crucial landmark for people in the region for centuries. Today, visitors come to experience how this historic structure connects past and landscape.

The area is accessible through marked trails that connect different points throughout the reserve, allowing visitors to explore the landscape at their own pace. The management office in Lanzo Torinese can provide guidance for your visit.

The giant's kettles behind the Chapel of San Rocco, at the Lanzo end of the bridge, are tied in legend to the devil: enraged at being tricked, he struck the rocks with his paws and left these hollows. The name Pont dël Ròch in Piedmontese means stone bridge.
