Janiculum

Built in honour of Victor Emmanuel, the first king of a unified Italy, this vast structure may appear to be solid white marble but actually contains many rooms inside. There are two permanent museums, one on Italian Reunification and one on emigration from Italy, as well as other spaces that host rotating exhibitions. A walk through the Flag Room leads to the tomb of the unknown soldier. Good views from half-way up but you can also pay €10 (€2 concessions) and take a lift all the way to the top.

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).

Although started in the 2nd century, San Callisto has had many more recent burials, including 16 popes. The burial arcades are almost 20 km long.

Parco Savello is the name of the grounds and orange grove next to the Santa Sabina church at the top of the Aventino and also where you have one of the best views of the city. Families gather here to sit under the dozens of orange trees. The "Giardino degli Aranci" is also a well known spot for lovers at night. The best views are arguably from Janiculum hill, just across the Tevere (Tiber) river. Immediately below you, the Tiber snakes its way through the city, and directly beyond it you can see the lively medieval quarter of Trastevere. Beyond that is the majestic dome of St. Peter's Basilica, with the historic centre of Rome visible to the right.

This building housed the University of Rome from the middle of the 15th century until 1935. The splendid interior courtyard was created by Giacomo della Porta. The inside church of Sant'Ivo (see above) is one of the masterpieces of the architect Borromini.

A strange building, constructed by Reginald Pole, an English cardinal and later Archbishop of Canterbury, allegedly on the spot where he was able to escape from assassins sent by the English King Henry VIII.

Brand new museum designed to celebrate the art and architecture of the 21st century.

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.

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

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.

A truly quiet oasis close to the hustle and bustle of EUR. There are three churches in this complex and the doors are open all day, unlike city churches. The monks produce a range of products such as liqueurs, chocolate and honey, as well as a cure for the illnesses Romans suffer when the Scirocco wind blows in from the Sahara. These are on sale at a shop at the Abbey.

In addition to Santa Maria in Cosmedin there is a lot to be seen around this piazza. Opposite the church is the round temple dedicated to Hercules Invictus (the Unconquered Hercules), and not far from that the rectangular Fortuna Virilis, both constructed in the 1st Century. Opposite, to the back of the piazza is the Arch of Argentari and behind that the church of San Giorgio in Velabro, the front of which was repaired after being damaged by a terrorist bomb in July 1993.

Contains the ruins of several large villas that belonged to wealthy Roman families. You can buy a combined ticket for the Palatine Hill, the Roman Forum and the Colosseum here, avoiding the long lines at the Colosseum. While the Imperial and Roman Fora are probably more spectacular, overall, there are amazing sights on the Palatine Hill, so unless you are terribly short on time or find it too challenging to climb the hill, allow an hour or more for these sights, too.

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.

According to the legendary passio, two brothers, John and Paul, who were officials at the imperial court, suffered martyrdom in 362 in their home on the Caelian hill, during the reign of emperor Flavius Claudius Julianus. This basilica dedicated to these two Roman officers was erected starting from 398 and was used first as a domus ecclesiae by the Christian community.
