The 26 meters high and 20 meters wide fountain is one of the most admired fountains in the world. Numerous attempts have been made to make the present fountain as magnificent as it is today.
All started in 19 B.C. when Marqus Agrippa built an aqueduct -Acqua Vergine- that provides pure drinking-water to the city of Rome. The Acqua Vergine acqueduct comes from Alban Hill, 13 km to the east of Rome, ending in the Quirinal Hill.
In 1453, Leon Battista Alberti financed by Pope Nicholas V, made a basin at the end of the Acqua Vergine (now called Trevi Fountain).
In 1629 Pope Clement XII appointed Gian Lorenzo Bernini to make necessary improvements to the works started by Leon Battista, unfortunately the works came to an end after the pope died.
Hundred years after the second attempt, Alessandro Galilei won a bid to make a better fountain but his opponent -Nicola Salvi- was awarded the mission because Romans murmured against Galilei (Florentine) who won away-commission.
Salvi died in 1751, leaving the work unfinished. The fountain was finished in 1762 by Guiseppe Pannini when Oceanus (god of all water) was fitted in place.
