繞著西方神話中的諸神，每一個雕像神態都不一樣，栩栩如生，諸神雕像的基座是一片看似零亂的海礁。噴泉的主體在海神的前面，泉水由各雕像之間、海礁石之間涌出，流向四面八方，最后又匯集于一處。
這個雄偉的噴線雕刻敘述的是海神的故事，背景建筑是一座海神宮，中間立著的是海神，兩旁則是水神，海神宮的上方站著四位少女，分別代表著四季。噴泉的設計者是沙維(Salvi)，于1762年才完工，因此是羅馬噴泉中比較年輕的一座。
許愿池是力量的象征。羅馬人有一個美麗的傳說，只要背對噴泉從肩以上拋一枚硬幣到水池里，就有機會再次訪問羅馬。很多旅游者在噴泉邊排著隊往里拋硬幣就是被這座城市迷住了的證明。噴泉的名字特雷維是三岔路的意思，因為噴泉前面有三條道路向外延伸，也正是噴泉名字的由來。
Standing as high as 25.9 meters (85 feet) wide and 19.8 meters (65 feet), the Trevi Fountain (Fontana di Trevi) has one of the most beautiful sculptures in Italy: Neptune or Oceanus in the middle and two triton, one trying to tame sea horses symbolize the cruel, and the other one blew the sea shells symbolizing peace. Ordered in 1732 by Clement XII and thirty years later his successor Clement XIII purified it.
Trevi became famous for a scene in the movie “La Dolce Vita” made by Fellini, Anita Ekberg as late-night drenched in this fountain. Also there is a legend that says, if you throw a coin into the Trevi Fountain, you will return to Rome.
