Orrido di Bellano

This guide to the Orrido di Bellano on Lake Como starts with a dispute nobody has settled: whether the Pioverna river spent fifteen million years or just one and a half million cutting this narrow gorge. It follows what the water did while it worked, gouging deep potholes into rock, and the stubborn engineering that anchored footbridges into the vertical walls rather than any ground. You'll also hear how ironworks and a cotton mill once put that same current to work, and what the Ca' del Diavol tower above the entrance was rumored to host.
