The Marmore Waterfall is the highest in Europe, with its 541 ft of height. It has been artificially created by the Romans in 3rd century b.C. to solve the problem of floods in the upper valley of Rieti. They channelled the Velino river towards the lower valley of Nera river, creating this incredible jump of water.
Marmore waterfall, described by poets and writers such as Byron and Goethe, was included in the Grand Tour, the Romantic 19th century itinerary touching the most beautiful venues of Italy.
Nowadays a number of sport activities can be practised in the area, including rafting, hydro-speed, canoeing, speleological visits and many others.
