Not too far from Narni, the Marmore Cascades are artificial waterfalls built by the Romans as part of larger waterworks. Water is here spectacularly deviated into the valley in three successive steps. Today, the falls have given rise to the building of a considerable tourist infrastructure, complete with shops, restaurants, a covered gallery from which the falls can be watched, and a shuttle bus taking visitors up and down along the path allowing a variety of perspectives on the falling water.
