Centrale Montemartini

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.

The Celian Hill is one of the seven hills of Rome. You immediately see the church of San Gregorio Magno. On this site monks were trained before setting off as missionaries to England at the end of the 6th Century. Further up the hill is Santi Giovanni e Paolo. At this point it is difficult to believe you are in the middle of a major city. This church was built in 398 over the home of two Roman soldiers, John and Paul, who were martyred for their Christian beliefs in 362. Excavations show that there were several burials on the site, a risky business as burials were illegal at that time. After the church you come to the back entrance of the Villa Celimontana park (jazz festival nightly in late June-August). The modern buildings before you reach the park are owned by Silvio Berlusconi’s television company. By the main entrance of the park note the boat-like fountain known as the “Navicella”. As you exit the main entrance to the left is the church of S. Maria in Domnica, which has some interesting mosaics. Next to this church is the Porta Esquilina, one of the gates from the original Servian walls of Rome. It dates back to the 4th century BC.

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.

This well-preserved Roman circus was built at the beginning of the fourth century. It was part of an imperial villa built by Maxentius and the complex also contains the Mausoleum of his son, Romolo.

The renamed Rome Zoo, one of the oldest in Europe, founded in 1911. On the edge of the Borghese Gardens, a short, well-signposted walk from the Gallery. They try hard, but San Diego this isn't. If you are a regular zoo-goer you will be disappointed.

Designed by Bramante to mark the spot of St. Peter's martyrdom, this delightful miniature building is considered a masterpiece of Renaissance architecture. Open to the public.

Ballroom-like church which crowns part of the Capitoline Hill. Don't be fooled by the plain stone exterior.

This is the island located in the middle of the Tiber River (Il Fiume Tevere) that separates Central Rome and Trastevere. It boasts both a major hospital, called Fatebenefratelli, and a small synagogue that was secretly used in the Second World War when Rome's main synagogue nearby was closed down. It also has a café and gelateria on the Rome side. It is a nice way of getting to and from Trastevere. Be sure to get photos from Ponte Garibaldi as Isola Tiberina truly is beautiful. The island is 270 m long and up to 67 m broad. According to the legend envoys were sent to the temple of Asklepius in Epidauros in Greece in 291BC in order to get relief from an epidemic in Rome. The envoys brought one of the holy snakes back with them. The snake swam to the Tiber Island thus determining the place where a temple for Asklepius was built. The successor of the Asklepius sanctuary is the Church San Bartolomeo which was built by the German Emperor Otto III around the year 1000. The Ponte Rotto is what is left from the ancient Pons Aemilius, the oldest stone bridge over the Tiber erected around 180 BC. The bridge was partly destroyed during a flood in 1557, re-erected by Pope Gregor XIII and finally pulled down in 1598. In 62 BC the Senatorial road construction office replaced the wooden footbridge by the Ponte Fabricio.

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 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.

Minor basilica in 17th-century baroque style with good art inside. In a smaller Italian city, this might be a prime attraction, but in Rome, with its abundance of great churches, this is merely a pleasant church of secondary interest to visit if you are in the area.

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.

The enormous building at the southeast end of the Circus Maximus is the headquarters of the UN Food and Agriculture Organization (FAO). From its roof are undoubtedly the best views of Rome, but you will need to know someone who works there to get past the strict security.
