Trevi Fountain is probably one of the most beautiful fountains in the world. Measuring some 20 meters in width by 26 meters in height, Trevi Fountain is also the largest fountain in Rome. The origins of the fountain go back to the year 19 B.C.: back then 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 from Tre Vie (three ways), since the fountain was the meeting point of three streets. Legend has it that if you throw one coin in the fountain you will return to Rome, if you throw two coins you will fall in love with an attractive Italian and that if you throw three coins you will marry the person that you met. An interesting statistic is that approximately a million euros worth of coins are taken from the fountain each year. Since 2007 this money has been used to support good causes.
