Introduction
The Trevi Fountain is an 18th-century Baroque fountain in the Trevi district of Rome, designed by architect Nicola Salvi and built using travertine stone, standing roughly 26 meters tall and 49 meters wide. It marks the terminal point of the ancient Virgo aqueduct, the only Roman aqueduct still in continuous use, and is famed for the tradition of visitors tossing coins into its waters.
