The Trevi Fountain is the largest and most famous fountain in Rome. The three central sculptures represent Neptune surrounded by two tritons, one trying to deal with an unruly seahorse, the other leading a calmer animal. They symbolize two conflicting states of the sea. The height of the fountain is 26 m, and the width is 20 m.

In the Middle Ages, the ancient aqueduct was dismantled, and its final branch became a spring, the water of which gushed into three small cavities. In the middle of the 15th century, Pope Michael V ordered the spring to be fenced and three taps installed. The idea to install a huge fountain here came from Urbon VIII in 1640. The most famous architect of that time, Gianlorenzo Bernini, was chosen as the author of the project.

After the death of the author of the original project, G. Bernini, further works on the construction of the fountain were undertaken by Klemens XII. He announced a competition in which 16 of Rome’s best architects participated. It was won by Nicola Salvi, who is considered the author of today’s fountain. The Trevi Fountain is also popular because of the legend, which says that in order to return to Rome again, it is necessary to throw a coin over the left shoulder with the right hand facing the fountain.
