Trevi Fountain, Rome

Rome's most famous fountain, a baroque masterpiece completed in 1762, with the sea god Oceanus riding a chariot pulled by sea horses, set against the façade of a palace. Tradition says that throwing a coin over your shoulder into the fountain means you'll return to Rome; the coins are collected for charity.

It's crowded day and night; go very early in the morning for a quieter view. Rome has introduced a small fee to go down to the edge of the fountain, while viewing from the square remains free. The Spanish Steps are a 10-minute walk away.
