The Trevi Fountain. At 85.3 feet high and 65.6 feet wide, this tower of travertine is a big, wet dream. No, not that kind. One of the most recognized monuments in Rome, it's where Anita Ekberg took a dip in her famous black dress in La Dolce Vita and where throwing in a coin means you'll return to the eternal city.
But what's beneath this fantastic facade? Turns out, the Trevi fountain is still fed by the Acqua Virgo, an ancient acqueduct built in the first century AD by Marcus Agrippa, and resides right above an ancient Roman street- the Vicus Caprarius. Although the Vicus Caprarius no longer remains, a HUGE complex of ancient ruins lie hidden beneath the Trevi fountain, dating to the Imperial age.
