Archbasilica of St. John Lateran

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 is not, contrary to popular belief, one of the original seven hills that Rome was founded on. It is the second highest after Monte Mario, though, and offers incredible panoramic views of the city as long as the authorities remember to prune the trees on the hillside (if they are too tall you can walk a few meters down the hill for views that are just as good). On the other side of the piazza there is also a nice view of the dome of St. Peter's. The Piazza and the street leading up the hill are dedicated to Giuseppe Garibaldi who led Italian troops against the French here in 1849. There are also several commemorative statues.

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.

This is one of the two main Jesuit churches in Rome, the other being the nearby Sant'Ignazio. The interior is Baroque art on steroids. Simply astounding.

This is a large tomb built by the Roman Emperor Augustus in 28 BC in the form of a stone ring covered by an earth mound. A brick wall, 87 m in diameter, carried an earth mound covered with cypresses. On top of the hill stood a bronze monument of the emperor. The building was 44 meters high. At the beginning of the alley, which led to the tomb were two Egyptian obelisks. On both sides of the doorway bronze plates describe the "Res gestae", the deeds of the emperor. The urns of Augustus, Marcellus, Octavia, Agrippa, Drusus and other members of the Julian Claudian dynasty were revered here. In the Middles Ages the building served as citadel of the Colonna family. It was destroyed by Pope Gregor IX in 1241. The body of Cola di Rienzo. a popular leader of the people in the mid-14th century, was burnt in this monument. The Mausoleo di Augusto is not open to the public, and is fenced off.

This is the island located in the middle of the Tiber River (Il Fiume Tevere) that separates Central Rome and Trastevere. It boasts both a major hospital, called Fatebenefratelli, and a small synagogue that was secretly used in the Second World War when Rome's main synagogue nearby was closed down. It also has a café and gelateria on the Rome side. It is a nice way of getting to and from Trastevere. Be sure to get photos from Ponte Garibaldi as Isola Tiberina truly is beautiful. The island is 270 m long and up to 67 m broad. According to the legend envoys were sent to the temple of Asklepius in Epidauros in Greece in 291BC in order to get relief from an epidemic in Rome. The envoys brought one of the holy snakes back with them. The snake swam to the Tiber Island thus determining the place where a temple for Asklepius was built. The successor of the Asklepius sanctuary is the Church San Bartolomeo which was built by the German Emperor Otto III around the year 1000. The Ponte Rotto is what is left from the ancient Pons Aemilius, the oldest stone bridge over the Tiber erected around 180 BC. The bridge was partly destroyed during a flood in 1557, re-erected by Pope Gregor XIII and finally pulled down in 1598. In 62 BC the Senatorial road construction office replaced the wooden footbridge by the Ponte Fabricio.

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.

A great little cathedral to visit, lovingly looked after by Irish Dominicans. There is an excavated older church below the medieval church you enter and a Mithraeum (temple to Mithras, whose cult was very popular with Roman soldiers from the 1st to 4th century AD) below that. The only place in Rome to hear the underground river that flows beneath the city.

The Servian Wall was the first wall around Rome, built around the 3rd century BC. This well-preserved section provides a good opportunity to observe the construction methods of that time, particularly the use of tufa rock blocks

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

More modern than most Roman churches: it was not started until 1873. This is Rome’s Episcopalian church. Some very interesting artwork, particularly the mosaics by Edward Burne-Jones of the Pre-Raphaelite school.

The temple of the Emperor Hadrian was consecrated in 145 AD by Emperor Antoninus Pius. The remains of the antique temple were incorporated into a new building that served as the Papal Customs House. It was finished around 1690 and today accommodates the Stock Exchange (Borsa).

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.

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.

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.
