According to the tradition, who throws a coin from the back inside Trevi's Fountain, one day will come back to Rome. Thousands of people every day throw a coin hoping one day to see Rome again. But where all these coins end up? Every day early in the morning, few cops surround the fountain and draw all the coins in with some pumps. They gather all the coins in bags and then they hand them over to some employees of the Caritas, one the biggest charity organizations in Rome. The tourists who throw the coins in the fountain hoping one day to come back to Rome, don't know that they are helping the poor and the homeless people of the city. The coins are eventually counted, separated and invested in charity by the Caritas. The coins of foreign currencies are periodically sent with some trucks in Germany and England where there are special organizations which can change them in euro. But how much money Trevi's Fountain can "produce"? A huge amount: roughly 700,000 euros per year, on average a bit less than 2,000 euros per day. This fountain doesn't only delight who looks at it but also helps plenty of needful people.
