This natural and monumental waterfall cascades in three thundering tiers over travertine cliffs cloaked in emerald Mediterranean forest, plunging a total of 165 meters into the misty gorge of the Nera River. Engineered by Roman consul Curius Dentatus in 271 BC to drain the marshy Velino River into the valley below, it stands today as the tallest man-made waterfall in the world, a rare fusion of ancient hydraulic ingenuity and untamed natural spectacle.

Set within the Parco Fluviale del Nera near Terni in Umbria, the falls roar to life at scheduled release times, when floodgates upstream unleash torrents of foaming white water that crash through limestone terraces, throwing up rainbows and clouds of fine spray visible for miles. Wooded trails wind along the gorge, offering panoramic belvederes over the cataracts, while the surrounding forest hums with birdsong and the constant murmur of falling water, making it one of Italy’s most evocative encounters between human engineering and wild landscape.
