That the Spanish Steps are actually French? The money to build them came from a French diplomat and the purpose was to connect the piazza at the bottom with the church of Trinita Dei Monti which was under the patronage of the Bourbon Kings of France and there are 138 steps.
That the Trevi Fountain collects 3,000 euro, which is used for the food bank and the foreign currency is donated to the Red Cross? The movie "Three Coins in the Fountain" transformed a once quiet piazza in Rome into a major tourist attraction. It also created a misconception that three coins, not just one, should be tossed into the Trevi Fountain. So to set the record straight: throw one coin over your left shoulder using your right hand and you will return to the eternal city; throw two coins and you will soon be married; throw three coins and your marriage will result in divorce!
That the movie "La Dolce Vita" with Anita Ekberg and Marcello Mastroianni was shot at night in the winter? Well, Anita Ekberg had no trouble standing in the freezing water in a completely soaked dress but Marcello Mastroianni needed a wet suit under his clothes. But that failed to keep him warm so he resorted to shots of vodka and as a result he was completely drunk when he filmed the scene!!
