The Trevi Fountain is at the ending part of the Aqua Virgo, an aqueduct constructed in 19 BC.
It brings water all the way from the Salone Springs (approx 20km from Rome) and supplies the fountains in the historic center of Rome with water.
In 1732, Pope Clement XII commissioned Nicola Salvi to create a large fountain at the Trevi Square.
A previous undertaking to build the fountain after a design by Bernini was halted a century earlier after the death of Pope Urban VIII.
Salvi based his theatrical masterpiece on this design. Construction of the monumental baroque fountain was finally completed in 1762.
