Perhaps the most famous fountain in the world, no trip to Rome will be complete without a visit to the Trevi Fountain. Located in the Quirinale district, an aqueduct built in 19BC by Agrippa brings water from the Salone Springs (21km from Rome) and supplies the fountains with water. Marvel at the impressive statue of Oceanus, of the divine personification of the sea, as he rides a shell-shaped chariot that is pulled by two sea horses. One is calm while the other is agitated, thus symbolising the ever-changing currents of the sea. The fountain spills an astonishing 80 million litres of water every day, but the water is recycled so you might want to think twice about drinking from it. Don’t forget to toss a coin inside too, as local traditions dictate. That ensures that you will return to Rome in the future.
