Piazza del Popolo

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.

One of Bernini's masterpieces, an obelisk on the back of an elephant.

The chains that allegedly held St. Peter are displayed in a case before the altar. More importantly, contains the impressive statue of Moses by Michelangelo. It's close to the Colosseum, but a little hard to find. Take the steps opposite the Colosseum on Via dei Fori Imperiali, cross the road at the top and seek directions. Also reachable through steps to the right leading off Via Cavour.

This pleasant park contains very well-preserved ruins of two aqueducts and some of the original surface of the Roman Via Latina. Gets crowded on Sundays but almost empty the rest of the week during term time. Good place for joggers.

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.

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.

One of the oldest churches in the city. The nave is lined with a mismatched collection of columns taken from ancient Roman buildings. The apse is covered in gold mosaics from the 13th century, arguably the finest mosaics in the city. Impressive mosaics also on the front. According to legend the church was founded in 222, so it would be one of the most ancient churches in the city. Written records mention a church on this place in 337. What is visible today was built in the 12th century, by order of Pope Innocent III. The facade is decorated with mosaics representing the Virgin Mary and ten unidentified figures. Most probably these mosaics are the work of Petro Cavallini who created the mosaics of the lower apse dated 1290 representing scenes from the life of Mary. The mosaics of the upper apse in byzantine style are even older and date from 1140. The columns of the nave originate from the ancient Baths of Caracalla. The facade of Santa Maria in Trastevere is even more impressive at night when it is illuminated.

Houses the tomb of St Lawrence. This basilica dates back to the 3rd century, when the area was already well populated. Surrounding it is Rome's cemetery, the Cimitero del Verano. San Lorenzo was damaged by Allied bombs in 1943 and the facade has been rebuilt.

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.

Wandering around the shopping and residential district of Prati, close to the Vatican, you may notice rather a lot of lawyers' nameplates outside buildings. This is also Rome's legal district because of the proximity of the Palazzo di Giustizia or Palace of Justice. This massive monstrosity on the banks of the Tiber was built on alluvial soil, which necessitated a concrete platform to support the foundations. Despite this, later settlement of the building led to the need for restoration work in 1970 and it is said to be still sinking. There were many allegations of corruption during its construction, something not unknown in the Rome of today, and this, combined with its appearance, gave rise to its nickname of the Palazzaccio or Ugly Palace.

Underground burial place of an ancient Roman family and of seven early popes.

On top of the Capitoline hill. The piazza was designed by Michelangelo. The Capitoline Museum is housed in the palaces flanking the piazza. You can walk behind the Palazzo Senatorio, where Rome's government meets, to a wonderful viewpoint which overlooks the entire Roman Forum. In the centre of the square you can admire an exact copy of the Statue of Marcus Aurelius on horseback; the original is kept in one of the two museums, to preserve it from pollution.

Perhaps the most fascinating building in Rome. The core of the structure began life as the mausoleum of Emperor Hadrian, built between 135 and 139 AD. Subsequent strongholds built on top of the mausoleum were in turn incorporated into a residence and castle by medieval Popes. The building was used as a prison until 1870 but now houses a museum. Opera buffs will be exhilarated to visit the balcony from which Tosca leaps to her death. Film buffs will recognise it as a setting from Angels and Demons.

Pope Sixtus IV della Rovere (1471-1481) gave order to replace the old Roman bridge by a new one. It was Pope Sixtus IV who also ordered the Sistine Chapel and the Opsedale di Santo Spirito to be built. So he ran out of money. He levied a tax on prostitution in order to gain money for the construction of the Ponte Sisto.

Casal Rotondo is the biggest mausoleum on the Appian Way, at about the sixth mile. It now incorporates a small private villa, originally a farmhouse. It is not known for whom it was built. The wall of fragments next to it, constructed by Luigi Canina, has ruins referring to the Cotta family but this family is now believed to not be associated with the Casal Rotondo.

This church is literally right next to the Pantheon. It is one of Rome's only Gothic churches, and well worth looking inside, although its plain square façade makes it look inconspicuous from outside. Excellent stained glass windows.

The first basilica was constructed in the 4th century and dedicated to San Sebastian, a martyr of the 3rd century. Sebastian's remains were transferred to St. Peter's in 826, prior to a Saracen assault when the church was destroyed. The current church was largely constructed in the 17th-century. Until the Great Jubilee in 2000 this was one of the Seven Pilgrim Churches of Rome, i.e. the churches that all Roman Catholic pilgrims were expected to visit. However, at that time it was replaced by the Sanctuary of Divino Amore (see below). Entrance to the catacombs, which are smaller than the others in the area, is to the right of the church entrance. The area where you buy tickets and wait for tours has a good display of sarcophagi from the catacombs. You can rent a bicycle at the catacombs for further exploration of the Appian Way.

This is a footbridge connecting Castel Sant'Angelo with the other side of the Tiber. It is a Roman bridge completed in 134 AD by Hadrian, to give access to his newly constructed mausoleum. Pilgrims used this bridge to reach St Peter's Basilica, hence it was earlier known as the "bridge of Saint Peter". In the seventh century, the castle and the bridge took on the name Sant'Angelo, when it is said that an angel appeared on the roof of the castle to announce the end of a plague. The statues of ten angels on the bridge reflect its name.

Where the building of the Italian Government, Palazzo Chigi is situated. Also there is a marvelous carved column—hence the name—dating back to Imperial Rome.
