Largo di Torre Argentina

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.

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.

A very ancient church named after a saint who was in 1969 removed from the Roman Catholic calendar of saints for the lack of details of her life. But the church retains the name and is well worth visiting for an excellent 4th-century mosaic and attractive decorations on the facade. Visiting hours are short, but if you arrive close to 11:30, try talking to the attendant if you see him, and he might let you visit for a few minutes. The church is small, so 15 minutes should be long enough to see and absorb everything.

This building housed the University of Rome from the middle of the 15th century until 1935. The splendid interior courtyard was created by Giacomo della Porta. The inside church of Sant'Ivo (see above) is one of the masterpieces of the architect Borromini.

Home of the President of the Italian Republic, and the Quirinal Gardens. Built in 1573 as a papal summer residence, and has since also served as the residence for the pope and later for the king of Italy.

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.

Unusual ancient Roman theatre with apartments built on top.

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.

The western end of the ancient Via Appia road connecting Rome to Brindisi in the heel of Italy, and as such the third world heritage site in Rome together with the Old Center and the Vatican. As such it's an important historical location, even if the remains of the gate aren't as impressive as the city's major sites. As Via Appia heads southeast out of Rome, and after a few kilometers the route is officially named Via Appia Antica and starts looking more historical: it gets narrow as a city street, the asphalt is replaced by a rock surface and the road is lined with parks and park-like areas and walled old buildings. This section has been described as the world's longest museum.

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

The museum is dedicated to Napoleon Bonaparte and his family. After Napoleon's death in 1821 the Pope gave permission to his family to settle down in Rome. His sister married Prince Camillo Borghese.

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.

Good collection of Renaissance and Baroque art, including by Velasquez, Titian, Raphael, and Bernini, all owned by the Doria Pamphilj family. Excellent audio guides really bring the paintings to life.

This is the attractive park on the hillside directly west of the Colosseum. Visible ruins in the area come from the Baths of Trajan. These baths were built on the top of the ruins of Domus Aurea - the Golden House of Nero (the Colosseum was built on the drained site of Nero's lake). The area underneath the park contains an enormous area from Nero's villa. It was restored at great expense in the 1980s and 1990s, opened to the public, and then closed again after a few years when it began to leak!

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.
