The Trevi Fountain is one of the most famous fountains in the world and universally known as one of the symbols of the Eternal City; it has also been filmed in many Italian and foreign movies. The fountain is considered a Baroque masterpiece; designed by Nicola Salvi, it is more than 25 metres tall and almost 50 metres large. The fountain is right at the end of a modern Roman aqueduct that replaced the ancient one which supplied pure water to the entire city.
Behind the Trevi Fountain the historic Palazzo Poli rises and it supports the complex group of sculptures that characterises this famous fountain. The main theme of the complex is the sea, featuring Oceanus with a shell chariot guided by tritons, taming hippocampus.
The fountain is also famous because of a worldwide known tradition that involves throwing a coin in the fountain while giving one’s back to Palazzo Poli with closed eyes. The origin of this custom is not exactly known, however people do it as a propitiatory act to wish themselves one day to come back to the Eternal City.
