Pigorini National Museum of Prehistory and Ethnography

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.

Built in honour of Victor Emmanuel, the first king of a unified Italy, this vast structure may appear to be solid white marble but actually contains many rooms inside. There are two permanent museums, one on Italian Reunification and one on emigration from Italy, as well as other spaces that host rotating exhibitions. A walk through the Flag Room leads to the tomb of the unknown soldier. Good views from half-way up but you can also pay €10 (€2 concessions) and take a lift all the way to the top.

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.

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

Church built on the site of three Roman pagan temples, which can be explored underground for a small fee paid at a desk near the church entrance.

They are posted at entrances to the Vatican City to provide security and protect the Pope. They wear very colourful clothing, similar to the uniforms worn by Renaissance-era soldiers. The Pontifical Swiss Guards is also the smallest and oldest standing army in the world, founded in 1506 by Pope Julius II. The origins of the Swiss guards, however, go back much further as the popes had regularly imported Swiss mercenaries during the 1400s.

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.

Casal Rotondo is the biggest mausoleum on the Appian Way, at about the sixth mile. It now incorporates a small private villa, originally a farmhouse. It is not known for whom it was built. The wall of fragments next to it, constructed by Luigi Canina, has ruins referring to the Cotta family but this family is now believed to not be associated with the Casal Rotondo.

Perhaps most famous for a large model of imperial Rome, but also has a large display of various aspects of ancient Rome, using plaster casts, models and reconstructions of works found in museums throughout the world.

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.

This is a large tomb built by the Roman Emperor Augustus in 28 BC in the form of a stone ring covered by an earth mound. A brick wall, 87 m in diameter, carried an earth mound covered with cypresses. On top of the hill stood a bronze monument of the emperor. The building was 44 meters high. At the beginning of the alley, which led to the tomb were two Egyptian obelisks. On both sides of the doorway bronze plates describe the "Res gestae", the deeds of the emperor. The urns of Augustus, Marcellus, Octavia, Agrippa, Drusus and other members of the Julian Claudian dynasty were revered here. In the Middles Ages the building served as citadel of the Colonna family. It was destroyed by Pope Gregor IX in 1241. The body of Cola di Rienzo. a popular leader of the people in the mid-14th century, was burnt in this monument. The Mausoleo di Augusto is not open to the public, and is fenced off.

A strange building, constructed by Reginald Pole, an English cardinal and later Archbishop of Canterbury, allegedly on the spot where he was able to escape from assassins sent by the English King Henry VIII.
