Catacomb of Callixtus

A pleasant fountain in an out-of-the-way square. It was originally meant to have four dolphins rather than turtles, but the dolphins proved to be too large for the water pressure, so the turtles were added as an afterthought.

The Catacombs of Domitilla are considered to be the best preserved of all Roman catacombs. They are the only ones still to contain bones. Domitilla also has a subterranean basilica, much of which was reconstructed in 1870.

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.

On top of the Capitoline hill. The piazza was designed by Michelangelo. The Capitoline Museum is housed in the palaces flanking the piazza. You can walk behind the Palazzo Senatorio, where Rome's government meets, to a wonderful viewpoint which overlooks the entire Roman Forum. In the centre of the square you can admire an exact copy of the Statue of Marcus Aurelius on horseback; the original is kept in one of the two museums, to preserve it from pollution.

More modern than most Roman churches: it was not started until 1873. This is Rome’s Episcopalian church. Some very interesting artwork, particularly the mosaics by Edward Burne-Jones of the Pre-Raphaelite school.

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

Caffarella Park covers an area of 339 ha and is part of the larger Appia Antica park. It contains both a working farm and numerous Roman ruins, some quite well preserved and is a great place for a stroll or cycle away from Rome’s traffic.

Located a short walk west of the Colosseum, this well-preserved monumental arch was erected (soon after 315) to commemorate the victory of Constantine, the first Christian emperor, over his rival Maxentius at the Battle of the Milvian Bridge in 312. In general design, the Arch of Constantine imitates the century-earlier Arch of Septimius Severus (nearby in the Forum). The three arches are decorated utilizing mainly materials plundered from other imperial monuments by Trajan, Hadrian and Marcus Aurelius. The quality of its sculptural decoration, however, betrays the slow degradation that Classical Roman sculpture had experienced in the 3rd century AD.

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 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.

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.

Early Roman houses dating back to the 1st century, believed to be homes of early Christians. Well-preserved frescoes and a small museum.

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.

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.
