Marmore Falls, the Cascata delle Marmore, is a tiered, man-made waterfall in Umbria, central Italy, 7.7 km from Terni and about 41 km southwest of Norcia in a straight line. At 165 metres it is the largest man-made waterfall in the world. In ancient times the Velino River fed a wetland in the Rieti Valley. In 271 BC the Roman consul Manius Curius Dentatus ordered a canal dug to divert the stagnant water over the cliff at Marmore into the Nera River below. The channel was re-dug and reworked many times over the centuries, until in 1787 the architect Andrea Vici reshaped the drops below the falls, giving them their present form. Heavy white water plunges in three tiers between densely wooded cliffs, spray rises in thick clouds, and rainbows often hang over the water. Below, the water runs between moss-covered rocks and turquoise pools. Visitors follow the paths between the upper and lower viewpoints, and many stand on a terrace close to the water to get soaked by the spray. The flow is controlled because the water is used for hydroelectric power, so check the opening times of the falls before visiting.
