The Cascata delle Marmore is an ancient artificial waterfall with a total height of 165 meters makes it the tallest man-made waterfall in the world.
It appears to have been created by the Romans as a means of mitigating perceived health risks from wetlands formed by the source of the waterfall, the river Velino.
The waterfall consists of three discrete sections with the topmost the tallest part at around 83 meters. It is located in the Italian region of Umbria, just under 8km from Terni.
Most of the time, the water in the canals above the falls is diverted to a hydroelectric power plant, so the flow in the falls themselves is heavily reduced. Piediluco Lake, above the falls, is used as a reservoir for the power plant. The Galleto power plant, built in 1929, is architecturally interesting. Its capacity is about 530 MW. To control the operation of the power plant, and to satisfy tourists, the falls are turned on according to a set schedule, achieving a spectacular effect at full flow.
