Church of the Gesù

Church built on the site of three Roman pagan temples, which can be explored underground for a small fee paid at a desk near the church entrance.

Early Roman houses dating back to the 1st century, believed to be homes of early Christians. Well-preserved frescoes and a small museum.

This palace of the 16th century was erected by the famous Medici family. It was the residence of Cardinals Giovanni and Giuliano Medici, later Pope Leo X. and Clement VII. Catherine de Medici, Pope Clement VII's niece lived here until her marriage in 1553 with Prince Henry, the son of King Francis I of France. The palace is named after Madama Margerita of Austria, the illegitimate daughter of Emperor Charles V. Since 1871 it has been the seat of the Italian Senate.

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.

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).

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.

The Scala Sancta (Holy Stairs) is, according to Roman Catholic tradition, the staircase used by Jesus Christ to approach Pontius Pilate to be sentenced to death. Attracts numerous pilgrims who climb the stairs on their knees.

This church can be an interesting deviation if you are passing through its neighbourhood. It is believed to be the grave of the Saints Ciro and Giovanni, killed during the time of the Emperor Diocletian. The original name was Abba Cyrus and through Appaciro and then Appacero it finally became Pacera, very close to today's Passera. The building is on top of a 3rd century building still visible in the lower floor and in the underground. The main part of the building dates back to the 9th century as do the frescoes on the higher floor. Some of the frescoes have been restored. Downstairs there is a small quadrangular room and the underground, where the remains of the two Saints are supposed to be. There are still visible 3rd century traces of Roman frescoes; in front of the stair you can enjoy a small bird, the Justice, and an athlete while in the vault some eight apex stars. Bus 128,780,781,775 (first stop in Via della Magliana).

Regular shows plus an excellent astronomical museum.

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

The most extensive collection of Etruscan art and artifacts anywhere. Fantastic collection and well worth the admission charge. A difficult museum to find, but a lovely display in a beautiful villa setting.
