Rome's largest and most famous monumental Trevi Fountain (1762).
As that song from the film of the same name goes "... 3 coins in the foun-tain!" (will pesos do?)

Legend runs that a young girl named Trivia led the exhausted troops of the consul Marcus Vispanius Agrippa to
drink at a spring 22 km/12 miles from the city which in her honor was named Aqua Virgo/Virgin. In 19 BC,
a terminal was made to direct its waters into a distribution system for Rome's new bath complexes.
