Santa Maria dell'Anima

By Bernini, in the very centre of Piazza Navona. Incorporates an Egyptian obelisk and symbolises four of the world's great rivers (the Ganges, the Nile, the Danube and the Plata), representing the four continents known at the time.

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.

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.

Built after 1631, the crypt of the church contains a macabre display - a series of chapels decorated with the bones of 3700 dead friars. The bones are glued to the walls and ceilings in bizarre and striking decorations.

Built in 141 AD and dedicated to the Empress Faustina; after her husband emperor Antoninus Pius died in 161 AD the temple was rededicated to the couple.

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.

A tomb for the wealthy Gaius Cestius, who died in 12 BC. Admission to the monument only by guided tours on specific dates (2nd and 4th Saturday every month, and in combination with a ticket to the Museum of Via Ostiense also on the 1st and 3rd Saturday of every month).

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).

This well-preserved Roman circus was built at the beginning of the fourth century. It was part of an imperial villa built by Maxentius and the complex also contains the Mausoleum of his son, Romolo.

It was constructed to hold relics of the Passion of Jesus. They include two thorns of his crown, part of a nail and three small wooden pieces of the Cross. The authenticity of these relics is much disputed, however.

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. 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.
