The most famous fountain in all of Rome - The Trevi Fountain. Located at about 10 mins walk frm the Pantheon, it is one of the most touristy of Rome's hotspots. Now for some trivia. "The central niche seems to impart movement to the imposing figure of Neptune who firmly guides a chariot drawn by sea horses, known as the � agitated � horse and the � placid horse �, names obviously derived from the way in which the two animals have been represented. As they gallop over the water, the horses are guided in their course by fine figures of tritons which emerge from the water and which were sculptured by P. Bracci in 1762. The setting all around consists of rocks." -- As you may have very well guessed, I did not figure all that out by myself, and chose instead to search on the Internet and copy-and-paste as it seemed so delightfully appropriate for the photograph.
