If you’ve been to Rome, you’ve seen the Trevi fountain, or you’ve gotten close enough to squeeze through a crack in the throng and come out somewhere within throwing distance of the big pool. But did you ever wonder, “where does that water go after tourists have gawked at it and thrown their coins in it?” For that, you have to go below the street surface of Rome, where they keep all the good, old stuff.

Vicus Caprarius – The City of Water, extends 9 meters below street level. The water that flows from the Trevi fountain, a monumental Baroque exhibition of the Virgin Aqueduct, Acquedotto Vergine (whose excavations brought to light an imposing distribution tank, the castellum aquae) and the water, which filters through the ancient masonry of the Archaeological area, continuing to supply the pipes in lead and the pools of a luxurious residence.
