Palazzo della Sapienza

A tomb for the wealthy Gaius Cestius, who died in 12 BC. Admission to the monument only by guided tours on specific dates (2nd and 4th Saturday every month, and in combination with a ticket to the Museum of Via Ostiense also on the 1st and 3rd Saturday of every month).

Inaugurated in 217 AD and used until the 6th Century. The baths were big enough for 1600 bathers at a time. Impressive and well-preserved. Used for operas in summer months (see Opera di Roma for details) and was the location for the famous "three tenors" concert in July 1990, at the time of the World Cup (soccer).

The building is in one of the most hidden corners of the city center among Piazza Navona and Castel Sant'Angelo. It served as residence for the Orsini family. Nowadays it is private property and one can only glance at the courtyard and the amazing fountain inside, erected in 1618 by architect Antonio Casoni. However, the brief moment is worth it.

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.

One of Bernini's masterpieces, an obelisk on the back of an elephant.

An underrated way to see fantastic art made after the Renaissance. Mainly Italian artists, notably De Chirico, but Cézanne, Degas, Kandinsky, Man Ray, Modigliani, Monet, Pollock and Van Gogh are also represented.

An example of urban planning that goes back to Pope Julius II, who, in 1508, envisioned it as a street that would connect all major government buildings. It is around a kilometer long and is in a straight line, an unusual feature for the time. It is lined with some interesting palaces but these days is more known for its antique shops. Via Giulia runs parallel with and one block from the River Tiber.

The Scala Sancta (Holy Stairs) is, according to Roman Catholic tradition, the staircase used by Jesus Christ to approach Pontius Pilate to be sentenced to death. Attracts numerous pilgrims who climb the stairs on their knees.

The temple of the Emperor Hadrian was consecrated in 145 AD by Emperor Antoninus Pius. The remains of the antique temple were incorporated into a new building that served as the Papal Customs House. It was finished around 1690 and today accommodates the Stock Exchange (Borsa).

This is one of the two main Jesuit churches in Rome, the other being the nearby Sant'Ignazio. The interior is Baroque art on steroids. Simply astounding.

Four fountains from the time of Pope Sixtus V when much of Rome was redeveloped. A reclining deity is the theme of each sculpture. This is a busy intersection and if you don't look twice you may miss these exquisite examples of Roman mythology.

Baroque church more noted for its position at the top of the Spanish Steps than it is for the church. Backdrop for numerous movies including Audrey Hepburn and Gregory Peck in Roman Holiday.

Also based on a Michelangelo architectural plan, this compact gallery is well endowed in classical sculpture and paintings. Highlights include the small 1st-century-BC bronze Lo Spinario, a Greek statue of a little boy picking a thorn from his foot; the Lupa Capitolina (Capitoline Wolf), a rare Etruscan bronze statue probably dating from the 5th century BC; and (in the entrance courtyard), the massive head, hands, foot and kneecap from a colossal statue of Constantine the Great. The palace also contains a Pinacoteca (Picture Gallery) with paintings mainly from the 16th and 17th centuries - highlights include: Caravaggio's Fortune-Teller and his curious John the Baptist; The Holy Family, by Dosso Dossi; Romulus and Remus, by Rubens; and Titian's Baptism of Christ.

According to the legendary passio, two brothers, John and Paul, who were officials at the imperial court, suffered martyrdom in 362 in their home on the Caelian hill, during the reign of emperor Flavius Claudius Julianus. This basilica dedicated to these two Roman officers was erected starting from 398 and was used first as a domus ecclesiae by the Christian community.

This impressive villa covers 23 hectares. It can be accessed from the Via Appia Nuova (Bus 118) or through Via Appia Antica 251. Parts can be seen from the Appian Way at around the 5th mile just after No 251. The villa was built by Maximus and Condinus Quintilii. The emperor Commudus liked it so much that he put the brothers to death in 182 AD and took it for himself. A museum has friezes and sculptures from the villa. The nypheum, the tepidarium and the baths may also be visited. At Appia Antica 251 is Santa Maria Nova, a farmhouse that has undergone many reincarnations since being built on top of a Roman cistern that was probably used by Villa dei Quintilii.
