3 Best Sights in Piazza di Spagna, Rome

The iconic Spanish Steps (often called simply la scalinata, or "the staircase," by Italians) and the Piazza di Spagna from which they ascend both get their names from the Spanish Embassy to the Vatican on the piazza—even though the staircase was built with French funds by an Italian in 1723. In honor of a diplomatic visit by the King of Spain, the hillside was transformed by architect Francesco de Sanctis with a spectacular piece of urban planning to link the church of Trinità dei Monti at the top with the Via Condotti below.

In an allusion to the church, the staircase is divided by three landings (beautifully lined with potted azaleas from mid-April to mid-May). Bookending the bottom of the steps are beloved holdovers from the 18th century, when the area was known as the "English Ghetto": to the right, the Keats-Shelley House and to the left, Babington's Tea Rooms—both beautifully redolent of the era of the Grand Tour.

For weary sightseers who find the 135 steps too daunting, there is an elevator at Vicolo del Bottino 8, next to the Metro entrance. (Those with mobility problems should be aware that there is still a small flight of stairs after, however, and that the elevator is sporadically closed for repair.) At the bottom of the steps, Pietro Bernini's splendid 17th-century Barcaccia Fountain still spouts drinking water from the ancient aqueduct known as the Acqua Vergine.

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.

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.
