Piazza del Campidoglio

This church, which was commissioned by Ferdinand and Isabella of Spain, marks the point where, according to tradition, St. Peter was crucified. Particularly interesting for Irish visitors as it contains the graves of three Gaelic Chiefs who fled Ireland in 1607.

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.

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.

The highest hill in Rome at 139 m, with sweeping views of the Vatican and Rome across the Tiber.

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

The pride of Baroque Rome, was established towards the end of the 15th century, and preserves the shape of the ancient Stadium of Domitian. The buildings surrounding the square stand where the spectators once sat, watching the spectacle of the naumachiae (battles among ships). The square remains completely unspoilt by traffic and modern buildings. Today, the square is an immensely popular place to sip a cappuccino, shop, and watch street performers. Behind the piazza at the northern end, you can still see remains of the Roman athletic stadium well below the current ground level. Amongst the various monuments of the square, look especially for the two Baroque masterpieces by Bernini and Borromini.

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

Baroque church more noted for its position at the top of the Spanish Steps than it is for the church. Backdrop for numerous movies including Audrey Hepburn and Gregory Peck in Roman Holiday.

The Collegio Romano was a college of the Jesuit order. Many popes, cardinals and bishops were educated here. Since 1870 it has been a secular (non-monastic) school. The coat of arms on the doorway is that of Pope Gregory XIII (1572–1585). The tower was erected in 1787 and served as an observatory. Until 1925 all clocks in Rome were set after that of the Collegio Romano.

This is an important place of pilgrimage for Catholics because of the supposedly miraculous powers of an image of the Virgin Mary. The first miracle was in 1740 when a traveller being attacked by a pack of dogs called out to the Virgin’s image for rescue and the dogs calmed down. The image was moved to Rome in the Second World War and is credited with saving the city from destruction, as a result of which Romans vowed to construct this new sanctuary.

Pope Nicholas III connected Castel Sant'Angelo to St. Peter's by a covered fortified corridor called the Passetto di Borgo. This proved useful for Pope Clement VII during the Sack of Rome (1527). You can still see much of the Passetto by walking along the Borgo Sant'Angelo, which runs parallel to, and north of, the Via della Conciliazione.

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.

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. The palace also contains a Pinacoteca (Picture Gallery) with paintings mainly from the 16th and 17th centuries - highlights include: Caravaggio's Fortune-Teller and his curious John the Baptist; The Holy Family, by Dosso Dossi; Romulus and Remus, by Rubens; and Titian's Baptism of Christ.

Unusual and fascinating round church dedicated to St. Stephen. It is the national church of Hungary in Rome. Dating from the 5th Century this is believed to be the largest round church in the world. Charles Dickens described its wall paintings of martyrdom and butchery as "hideous". A good starting point to visit the attractions of the Celio Hill (see Rome/Aventino-Testaccio).

With its strange Liberty- style buildings with influence from the Art Nouveau of the 1920s this small bunch of blocks is one of the most interesting, and less known, landmarks of the city. A must see.

This church is roughly halfway between Piazza Navona and the Pantheon. It is most notable for a side chapel which contains three Caravaggio masterworks: "The Calling of St. Matthew", "St. Matthew and the Angel" and "Martyrdom of St. Matthew".

According to an inscription Emperor Augustus dedicated the obelisk to the sun in the 11th year of his consulate (10BC), after he had annexed Egypt to Rome. The obelisk is 24 m high. It was erected in Heliopolis in Egypt and was dedicated to Pharao Sethos I (1313-1292 BC) and Pharoa Ramses II (1292-1275 BC). Augustus brought the obelisk to the Circus Maximus, where it was rediscovered in 1587, broken into three pieces and was relocated to Piazze del Popolo on the orders of Pope Sixtus V in 1589.

Home of the Abbot Primate of the Benedictine Confederation and Benedictine monks studying in Rome. Visit the monastic produce shop and listen to the best Gregorian chant in Rome during Vespers (19:15 each evening).

This small museum records the liberation of Rome from German occupation during the Second World War. During the occupation the building was used as a prison. Stair lifts and chair lifts available for wheelchair users (call ahead).

On the site of the Roman baths, this museum houses an enormous collection of statues, etc.
