Circus of Maxentius

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.

A truly monumental stairway of 135 steps (similar to climbing eight flights of stairs), built with French funds between 1721 and 1725 in order to link the Bourbon Spanish embassy to the Holy See (still located in the piazza below), with the Bourbon French church (its monastery founded in 1495) above. Don't sit on them though, or eat, or push a baby stroller on them, or do anything else that might obstruct pedestrians, make them dirty, or cause additional wear and tear, or else you will have to pay a fine that ranges from €250 to €400.

Where you can find the building of the House of Representatives.

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

A large villa and 180-ha park that is a major recreation area for Romans, and a popular spot for joggers. One unusual feature of the grounds is the colony of coypus (swamp beavers) around the lake. Natives of South America these ones are descended from some who wisely escaped from a fur farm. There are also colonies by the Tiber.

On the other side of the Via dei Fori Imperiali to the Roman Forum. Well-preserved market area that doubled as a way of stopping the Quirinal Hill from collapsing. Below in the Forum is Trajan's Column, built in 113 with reliefs depicting the Emperor Trajan's vistories in battle.

A truly quiet oasis close to the hustle and bustle of EUR. There are three churches in this complex and the doors are open all day, unlike city churches. The monks produce a range of products such as liqueurs, chocolate and honey, as well as a cure for the illnesses Romans suffer when the Scirocco wind blows in from the Sahara. These are on sale at a shop at the Abbey.

A 19th-century addition to the square, made to balance the Fontana del Moro.

The contours of the ancient stadium, built in the 6th Century B.C., are still visible in what is now a park in the shadow of the Palatine. Circus Maximus was primarily devoted to chariot races and was used for this purpose until around 550 AD. The stadium could seat up to 150,000 people. Originally built of wood, it burnt down twice, on the second occasion starting the great fire when the Emperor Nero was said to fiddle while Rome burned. It was in one of the tunnels here that Caligula met his end. Excavations began in 2009 at the east end of the circus and are likely to go on for some years.

This church was built next to the mausoleum of Santa Costanza in the 7th Century and is on top of catacombs. It is very unusual in that the floor level is at the level of the catacomb floor, and the street entrance is at the level of the second floor gallery. The body of St. Agnes lies in a silver sarcophagus. There are several stories about her death at the age of 13 in 304 AD. One is that the prefect Sempronius wanted her to marry his son, and condemned her to death when she refused. Roman law did not permit the execution of virgins, so he ordered her to be raped but her virginity was miraculously preserved. She was then condemned to be burnt at the stake but the wood would not burn. Another is that she was stripped naked by the Emperor Diocletian because of her refusal to marry but that her hair then grew rapidly to preserve her modesty.

One of the most splendid (still private) Baroque grand palaces in Rome.

A great little cathedral to visit, lovingly looked after by Irish Dominicans. There is an excavated older church below the medieval church you enter and a Mithraeum (temple to Mithras, whose cult was very popular with Roman soldiers from the 1st to 4th century AD) below that. The only place in Rome to hear the underground river that flows beneath the city.

In the 8th and 9th century, San Saba was one of the most prestigious monasteries of Rome. The church has been built up over many centuries and contains a variety of architectural styles. Worth a look are the floor mosaics and some interesting frescoes on the left side of the church.

Beautiful park, the 2nd largest in Rome (after Villa Doria Pamphili) at 450 acres/182 hectares. Hosts concerts on summer evenings. former summer residence of Italian monarchs. Also known for it's bunker.

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.

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.

This church is literally right next to the Pantheon. It is one of Rome's only Gothic churches, and well worth looking inside, although its plain square façade makes it look inconspicuous from outside. Excellent stained glass windows.

Perhaps the most fascinating building in Rome. The core of the structure began life as the mausoleum of Emperor Hadrian, built between 135 and 139 AD. Subsequent strongholds built on top of the mausoleum were in turn incorporated into a residence and castle by medieval Popes. The building was used as a prison until 1870 but now houses a museum. Opera buffs will be exhilarated to visit the balcony from which Tosca leaps to her death. Film buffs will recognise it as a setting from Angels and Demons.

Contains the ruins of several large villas that belonged to wealthy Roman families. You can buy a combined ticket for the Palatine Hill, the Roman Forum and the Colosseum here, avoiding the long lines at the Colosseum. While the Imperial and Roman Fora are probably more spectacular, overall, there are amazing sights on the Palatine Hill, so unless you are terribly short on time or find it too challenging to climb the hill, allow an hour or more for these sights, too.

This archaeological site displays the thermal baths of the villa of the wealthy Herod Atticus. Also in the complex is a restored villa, until 2002 a private residence, that has an exterior completely covered with pieces from Roman ruins, including pipes used in the baths. There are some very helpful staff to show you around, although they only speak Italian. An interesting photographic exhibition in the house traces the development of the Appian Way over the last century. Almost opposite the entrance to the baths is a ruined tower known as the Torre di Capo di Bove.
