San Pietro in Vincoli

Known properly as the Flavian Amphitheatre, this most famous of Roman landmarks takes its name from the giant statue of the emperor Nero that once stood near this location. The amphitheatre was capable of seating 50,000 spectators for animal fights and gladiatorial combats. It was a project started by the Emperor Vespasian in 72 and completed by his son Domitian sometime in the 80s. The Colosseum when completed measured 48 m high, 188 m in length, and 156 m in width. The wooden arena floor was 86 m by 54 m, and covered by sand.;Expect a long queue and an even longer wait. You can skip the queue if you decide to take a tour, but if you don't want a tour, you can STILL skip the queue. If you walk to the entrance for the Roman Forum, you can buy tickets there which allow you to bypass the queues. You can also buy tickets online. There are lots of people offering tours in English just outside the entrance to the Colosseum. Inside you can take a tour (English, Spanish, or German) every 30 minutes or so for an additional fee. The tours are given by knowledgeable archeologists, but they don't take you to any areas you couldn't visit on your own.

Romans and leaders of Rome's defeated enemies were imprisoned here where they either died of starvation or strangulation. According to legend, St. Peter was also imprisoned here.

It was immortalised in 1960 by the Federico Fellini film La Dolce Vita. It is also the location of the US Embassy, in the massive Palazzo Margherita. Via Veneto went into a period of decline in the 1980s but has returned to popularity and the roadside cafes are the place to be seen if you are into that sort of thing.

According to an inscription Emperor Augustus dedicated the obelisk to the sun in the 11th year of his consulate (10BC), after he had annexed Egypt to Rome. The obelisk is 24 m high. It was erected in Heliopolis in Egypt and was dedicated to Pharao Sethos I (1313-1292 BC) and Pharoa Ramses II (1292-1275 BC). Augustus brought the obelisk to the Circus Maximus, where it was rediscovered in 1587, broken into three pieces and was relocated to Piazze del Popolo on the orders of Pope Sixtus V in 1589.

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

The mausoleum of Cecilia Metella, who died in 69 BC, is the best preserved monument on the Appian Way and dominates the surroundings. In the Middle Ages it was transformed into a fortress and battlements were added. At that time there was considerable competition for ownership because of its strategic location.

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.

Fantastic Byzantine mosaics and some other interesting artwork. Not to be missed. 30 minutes are sufficient for a relaxed visit.

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.

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.

The two museums are on opposite sides of the Piazza del Campidoglio, It is recommended to book tickets online Built in the 17th century to a design based on an architectural sketch by Michelangelo. Highlights include the ancient Colossus of Constantine statue (the Colosseum was probably named for another giant statue, the Colossus of Nero which stood near the Flavian Amphitheatre as the Colosseum was originally known), The Dying Gaul, a magnificent marble sculpture that copies a bronze Greek original of the 3rd century BC and the Capitoline Venus. It also contains the remarkable original gilt bronze equestrian statue of emperor Marcus Aurelius (the one in the piazza is a replica). 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.

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.

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.

One of the oldest churches in the city. The nave is lined with a mismatched collection of columns taken from ancient Roman buildings. The apse is covered in gold mosaics from the 13th century, arguably the finest mosaics in the city. Impressive mosaics also on the front. According to legend the church was founded in 222, so it would be one of the most ancient churches in the city. Written records mention a church on this place in 337. What is visible today was built in the 12th century, by order of Pope Innocent III. The facade is decorated with mosaics representing the Virgin Mary and ten unidentified figures. Most probably these mosaics are the work of Petro Cavallini who created the mosaics of the lower apse dated 1290 representing scenes from the life of Mary. The mosaics of the upper apse in byzantine style are even older and date from 1140. The columns of the nave originate from the ancient Baths of Caracalla. The facade of Santa Maria in Trastevere is even more impressive at night when it is illuminated.

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.

Pope Sixtus IV della Rovere (1471-1481) gave order to replace the old Roman bridge by a new one. It was Pope Sixtus IV who also ordered the Sistine Chapel and the Opsedale di Santo Spirito to be built. So he ran out of money. He levied a tax on prostitution in order to gain money for the construction of the Ponte Sisto.

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.
