Mausoleum of Augustus

This little church is hard to find but well worth the extra effort although it is often closed when you get there. One of Borromini's masterpieces. It is located only a block from Piazza Navona, but not usually visible from the street, as you must enter the courtyard of an old palazzo to reach the church. Sant'Ivo is a small church the dome of which is shaped like the Star of David, but with every other point rounded. The steeple seen from the outside looks like it has a staircase wrapped around it that ascends to heaven. As the church was commissioned by the Barberini family that produced a number of popes and whose family symbol was the bee—some say the steeple resembles the stinger of the insect.

Simple and elegant lines make up this building, whose construction began in 1480 for Count Girolamo Riario, nephew of Papa Sisto IV, and was taken up by architect Martino Longhi for the new owner, Cardinal Marco Sittico Altemps. Today it houses one of the branches of the National Museum of Rome, showcasing ancient and Renaissance sculptures, and the results of the 16th/17th-century fashion for 'completing' ancient sculptures missing heads or arms.

This is a treasure-trove of art. There are a couple of paintings by Caravaggio: "The Crucifixion of Saint Peter" and "The Conversion of Saint Paul" (in a dim alcove to the left of the altar, both at right angles to the viewer, with a machine wanting €2 to switch on the lighting) together with a sculpture by Bernini, frescoes by Pinturicchio and mosaics by Raphael. Part of the Dan Brown tour, this church featured in Angels and Demons, although the Vatican did not allow filming inside.

Built in 141 AD and dedicated to the Empress Faustina; after her husband emperor Antoninus Pius died in 161 AD the temple was rededicated to the couple.

Regular shows plus an excellent astronomical museum.

If it is sunny, you'll catch a few young people and older gentlemen sitting at the base of a statue in the middle of the open space. The statue is a brooding, hooded Giordano Bruno—an excommunicated Dominican monk and one of the earliest cosmologists who held the idea of an infinite universe. He was burnt at the stake for heresy on this spot on 17 February 1600. The piazza is used as a marketplace during the day, and party central for college students and tourists at night. When the sky gets dark and the street lamps go on, the Campo de' Fiori fills with people and lovers wander arm in arm in the crowd. Over the buzzing of conversation and the occasional burst of laughter you may hear a young vocalist belt out O Sole Mio at the top of his lungs as change plunks into his accordion case.

This church, which was commissioned by Ferdinand and Isabella of Spain, marks the point where, according to tradition, St. Peter was crucified. Particularly interesting for Irish visitors as it contains the graves of three Gaelic Chiefs who fled Ireland in 1607.

A strange building, constructed by Reginald Pole, an English cardinal and later Archbishop of Canterbury, allegedly on the spot where he was able to escape from assassins sent by the English King Henry VIII.

In addition to Santa Maria in Cosmedin there is a lot to be seen around this piazza. Opposite the church is the round temple dedicated to Hercules Invictus (the Unconquered Hercules), and not far from that the rectangular Fortuna Virilis, both constructed in the 1st Century. Opposite, to the back of the piazza is the Arch of Argentari and behind that the church of San Giorgio in Velabro, the front of which was repaired after being damaged by a terrorist bomb in July 1993.

The remains of the ancient Roman archives, where Cicero and Seneca did research. Visible from the Forum and accessible through the Capitoline Museum.

A lovely, if somewhat run-down park (parts of it are blocked due to the poor state of the roads) with statues and a great view on the city.

At the southern end of the Piazza, designed by Bernini but the main statue of the Moor was done by Giacomo della Porta and the other statues are 19th-century copies of the originals.

More of an enormous traffic circle than a piazza, but a good central location. The centerpiece is the enormous Vittorio Emanuele Monument (aka the Wedding Cake or the Typewriter) with the Capitoline hill next door. Mussolini used to harangue Romans from the first floor balcony of Palazzo Venezia (see under Museums), to the west of the square.

This is an important place of pilgrimage for Catholics because of the supposedly miraculous powers of an image of the Virgin Mary. The first miracle was in 1740 when a traveller being attacked by a pack of dogs called out to the Virgin’s image for rescue and the dogs calmed down. The image was moved to Rome in the Second World War and is credited with saving the city from destruction, as a result of which Romans vowed to construct this new sanctuary.
