Arch of Constantine

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

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.

With Bernini's famous Triton Fountain. Via Veneto starts here too.

A very small and beautiful church, the first design commission of Francesco Borromini.

The palace was built by the architect Baldassare Peruzzi on behalf of the Massimo family. The former palace was destroyed during the pillage of Rome in 1527. The Massimo family can be traced back to Quintus Fabius Maximus who defeated Hannibal in the 3rd century BC. The building is open to the public on March 16, only in order to commemorate the miraculous reanimation of Paolo Massimo by St. Philip Neri in 1538.

This massive early 17th-century Baroque fountain was built to celebrate the re-opening of an old Roman aqueduct. Water played an important role in this area in Roman times as the grain was milled here using water mills.

Regular shows plus an excellent astronomical museum.

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.

This is not the real name of the church on the corner by the main entrance to San Callisto but it is universally known by this name. By legend it is located on the spot where Saint Peter had a vision of the risen Christ while fleeing persecution in Rome. According to the tradition, Peter asked Jesus, Domine, quo vadis? “Lord, where are you going?” The current church is from 1637. Inside is a copy of a stone said to contain the imprints of the feet of Jesus; the original is maintained in San Sebastiano, further along the Appian Way

Porta San Sebastiano is a gate in the amazingly well-preserved Aurelian Walls. Inside and upstairs is a museum dedicated to the construction of the walls and their recent restoration. You can take a walk along the top of the walls. At the museum you can also arrange to visit the Tomb of the Scipios (Sepolcro degli Scipiani) and a nearby Roman Columbarium (tomb for cremated remains), the entrance for which is 200 m back towards Rome along the Via Di Porta San Sebastiano. No wheelchair access.

The building is in one of the most hidden corners of the city center among Piazza Navona and Castel Sant'Angelo. It served as residence for the Orsini family. Nowadays it is private property and one can only glance at the courtyard and the amazing fountain inside, erected in 1618 by architect Antonio Casoni. However, the brief moment is worth it.

A medieval church dating from the 6th century and home to the Bocca della Verità (Mouth of Truth). The Bocca della Verità at the entrance to the church is thought to be a 1st-century manhole cover. It is believed that if you put your hand in the mouth and tell a lie, the hand will be bitten off. Queues for the privilege of risking this can get rather long. Don't ignore the church, which is a gem, and has a separate entrance. Its mosaic floor in the Cosmatesque style is more rustic and less intricate than some others (Santa Maria in Trastevere, for example), but its simplicity gives it a solidity not found in the more ornate styles. S.M. in Cosmedin has a fine medieval choir enclosure and the tallest medieval belfry in Rome.

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.

This is the cathedral church of Rome and first of the major basilicas. It's also the Pope's (as Bishop of Rome) Church. As such it ranks above all other churches in the Roman Catholic Church, even above St. Peter's. Be sure to check out the 4th-century baptistery (still in use - in Piazza di San Giovanni, slightly apart from the main basilica) and the medieval cloister (brilliant Cosmati columns)

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.

This remarkable building, designed partly by Bernini, houses the National Gallery of Ancient Art, and includes some famous paintings by Filippo Lippi and Caravaggio, as well as Raphael's "La Fornarina".

At the northern end of Via XX Settembre next to the Porta Pia designed by Michaelangelo. The previous embassy had been destroyed by a terrorist bomb in 1946 and was eventually replaced by this world-renowned modern design by Sir Basil Spence. It was built on stilts so as not to interrupt the view of the garden.

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.
