This fountain stands 86 ft high and 131.6 ft wide and is the largest Baroque fountains in Rome and one of the most beautiful in the world. The origins of the fountain go back to the year 19 B.C., in which period the fountain formed the end of the Aqua Virgo aqueduct. The first fountain was built during the Renaissance, under the direction of Pope Nicholas V.
The final appearance of the Trevi Fountain dates from 1762, when after many years of works at the hand of Nicola Salvi, it was finalized by Giuseppe Pannini.
Interestingly enough, the name of Trevi derives Tre Vie (three ways), since the fountain was the meeting point of three streets.
The myth, originating in 1954 with the movie "Three Coins in the Fountain," goes like this:
If you throw one coin: you will return to Rome.
If you throw two coins: you will fall in love with an attractive Italian.
If you throw three coins: you will marry the person that you met.
In order to achieve the desired effect, you should throw the coin with your right hand over your left shoulder.
