10 Best Sights in Italy

Alive with rushing waters commanded by an imperious sculpture of Oceanus, the Fontana di Trevi has been all about theatrical effects from the start; it is an aquatic marvel in a city filled with them. The fountain's unique drama is largely due to its location: its vast basin is squeezed into the tight confluence of three little streets (the tre vie, which may give the fountain its name), with cascades emerging as if from the wall of Palazzo Poli.

The dream of a fountain emerging full force from a palace was first envisioned by Bernini and Pietro da Cortona from Pope Urban VIII's plan to rebuild an older fountain, which had earlier marked the end point of the Acqua Vergine, an aqueduct created in 18 BC by Agrippa. Three popes later, under Pope Clement XIII, Nicola Salvi finally broke ground with his winning design. Unfortunately, Salvi did not live to see his masterpiece of sculpted seashells, roaring sea beasts, and diva-like mermaids completed; he caught a cold and died while working in the culverts of the aqueduct 11 years before the fountain was finished in 1762.

Everyone knows the famous legend that if you throw a coin into the Trevi Fountain you will ensure a return trip to the Eternal City, but not everyone knows how to do it the right way. You must toss a coin with your right hand over your left shoulder, with your back to the fountain. One coin means you'll return to Rome; two, you'll return and fall in love; three, you'll return, find love, and marry. The fountain grosses some €1,500,000 a year, with every cent going to the Catholic charity Caritas, which is why Fendi was willing to fully fund the Trevi's recent restoration.

Tucked away in a little nearby alley is the Vicus Caprarius ( Vicolo del Puttarello, 25), a small museum where visitors can pay €8 for a guided tour that descends into a subterranean area that gives a glimpse at the water source that keeps the fountain running.

Sculptor Giambologna's elaborate 1563–66 Baroque fountain and monument to Neptune occupying Piazza Nettuno has been aptly nicknamed "Il Gigante" (The Giant). Its exuberantly sensual mermaids and undraped god of the sea drew fire when it was constructed—but not enough, apparently, to dissuade the populace from using the fountain as a public washing stall for centuries.

When Pope Sixtus V (Felice Peretti) completed the restoration of the Acqua Felice aqueduct toward the end of the 16th century, Domenico Fontana was commissioned to design its monumental fountain. Sculptors Leonardo Sormani and Prospero da Brescia had the unhappy task of executing the central figure of Moses; the comparison with Michelangelo's magnificent Moses in the church of San Pietro in Vincoli was inevitable, and the giant sculpture was widely criticized. But the new fountain served to position the formerly rustic Quirinale neighborhood as a thriving urban center.

The underground Amenano River flows beneath much of Catania. You can glimpse it at the Fontana dell'Amenano, a Carrara marble fountain on the Piazza del Duomo that was built in 1867. It's a popular meeting point and tourist attraction. However, one of the best places to experience the river is at the bar-restaurant A Putia dell'Ostello ( Piazza Currò 6  095/7233010  www.agorahostel.com). Here you can sit at a lantern-lit underground table as the water swirls through. If you're not planning to stay for a drink, someone from the bar will sell you a €1 ticket to walk into the cavelike seating area. Aside from the underground river, the bar area aboveground is a lively, fun spot to hang out on a Monday evening when many other places are closed.

At the foot of the Spanish Steps, this curious, leaky boat fountain is fed by Rome's only surviving ancient aqueduct, the Acqua Vergine. The sinking ship design is a clever solution to low water pressure and was created by Pietro Bernini, with the help of his son, the prolific sculptor Gian Lorenzo Bernini. The project was commissioned by Barberini Pope Urban VIII, and the bees and suns on the boat are symbols of the Barberini family. Looking for more symbolism, some insist that the Berninis intended the fountain to be a reminder that this part of town was often flooded by the Tiber; others claim that it represents the Ship of the Church; and still others think that it marks the presumed site of the emperor Domitian's water stadium in which sea battles were reenacted in the glory days of the Roman Empire.

The upper shell and inscription of this fountain, which is decorated with the famous heraldic bees of the Barberini family, are from a fountain that Bernini designed for Pope Urban VIII; the rest was lost when the fountain was moved to make way for a new street. The inscription caused considerable uproar when the fountain was first built in 1644. It said that the fountain had been erected in the 22nd year of the pontiff's reign, although, in fact, the 21st anniversary of Urban's election to the papacy was still some weeks away. The last numeral was hurriedly erased, but to no avail—Urban died eight days before the beginning of his 22nd year as pope. The superstitious Romans, who had regarded the inscription as a foolhardy tempting of fate, were vindicated.

Designed by Giacomo della Porta in 1581 and sculpted by Taddeo Landini, this fountain, set in pretty Piazza Mattei, is one of Rome's most charming. Its focal point consists of four bronze boys, each grasping a dolphin spouting water into a marble shell. Bronze turtles just out of reach of the boys' hands drink from the upper basin. The turtles were added in the 17th century by Bernini.

A freshwater spring, the Fountain of Arethusa sits next to the sea, studded with Egyptian papyrus that's reportedly natural. This anomaly is explained by a Greek legend that tells how the nymph Arethusa was changed into a fountain by the goddess Artemis (Diana) when she tried to escape the advances of the river god Alpheus. She fled from Greece, into the sea, with Alpheus in close pursuit, and emerged in Sicily at this spring. It's said if you throw a cup into the Alpheus River in Greece, it will emerge here at this fountain, which is home to a few tired ducks and some faded carp—but no cups. If you want to stand right by the fountain, you need to gain admission through the aquarium; otherwise look down on it from Largo Aretusa.

The square's centerpiece, a lavishly decorated fountain with 500 separate pieces of sculpture and an abundance of nude figures, so shocked some Palermitans when it was unveiled in 1575 that it got the nickname "Fountain of Shame." It's even more of a sight when illuminated at night. Sadly, there is no water in the fountain at present while it awaits a major repair.

This central square houses an elaborate 18th-century Baroque water fountain whose mountain water source has been vital for centuries. The Fontana dei Quattro Cannoli was once the social and commercial heart of the medieval city.
