Piazza di Monte Citorio

A 1st-century tomb surrounded by two farmhouses from the Middle Ages, one of which used to be a cheese store. Rather hidden behind a high wall, the tomb is rarely open to the public. You might be lucky on a Sunday: on the third Sunday of every month there is a guided tour at 11:00.

The 4th rebuilding of the meeting place for the Roman Senate, once converted into a church during the Middle Ages, but now restored since the 1930s.

Inaugurated in 217 AD and used until the 6th Century. The baths were big enough for 1600 bathers at a time. Impressive and well-preserved. Used for operas in summer months (see Opera di Roma for details) and was the location for the famous "three tenors" concert in July 1990, at the time of the World Cup (soccer).

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.

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.

Next door to Santa Croce. A collection of around 3000 pieces, although only a third of these are displayed.

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.

Next door to the Pyramid, this fine gate in the Aurelian Wall is named after St. Paul as the Via Ostiense leads to the basilica of St. Paul's Outside the Walls (see Rome/South).

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.

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

The house in which the famous English poet John Keats succumbed to consumption, now preserved as a memorial to his life and that of his friend Shelley, both of whom are buried in Rome's Protestant Cemetery (see Testaccio).

Completed in 179 BC.

The Ghetto lies between the island in the River Tiber and the Theatre of Marcellus and includes Rome’s synagogue. It was established in 1555 as a result of a Papal Bull by Pope Paul IV that required all Jews to live in the area, considered one of the least desirable quarters of the city, as it was subject to constant flooding by the river. The area was originally enclosed by walls and gates that were only open during the day. With the end of the Papal States in 1870, the requirement that Jews live in the Ghetto came to an end. The walls were torn down in 1888 and much of the ghetto was demolished. However, there is still much to see, including walls of buildings that incorporate Roman ruins, and there are several good Jewish restaurants.

An ancient Egyptian obelisk brought to Rome in 10 BC.

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.
