Palazzo della Sapienza

The western end of the ancient Via Appia road connecting Rome to Brindisi in the heel of Italy, and as such the third world heritage site in Rome together with the Old Center and the Vatican. As such it's an important historical location, even if the remains of the gate aren't as impressive as the city's major sites. As Via Appia heads southeast out of Rome, and after a few kilometers the route is officially named Via Appia Antica and starts looking more historical: it gets narrow as a city street, the asphalt is replaced by a rock surface and the road is lined with parks and park-like areas and walled old buildings. This section has been described as the world's longest museum.

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 is not the real name of the church on the corner by the main entrance to San Callisto but it is universally known by this name. By legend it is located on the spot where Saint Peter had a vision of the risen Christ while fleeing persecution in Rome. According to the tradition, Peter asked Jesus, Domine, quo vadis? “Lord, where are you going?” The current church is from 1637. Inside is a copy of a stone said to contain the imprints of the feet of Jesus; the original is maintained in San Sebastiano, further along the Appian Way

Regular shows plus an excellent astronomical museum.

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.

An ethnographic collection of around 60,000 pieces from European indigenous cultures. Documents evolution from the Palaeolithic age to the Iron Age.

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 is the attractive park on the hillside directly west of the Colosseum. Visible ruins in the area come from the Baths of Trajan. These baths were built on the top of the ruins of Domus Aurea - the Golden House of Nero (the Colosseum was built on the drained site of Nero's lake). The area underneath the park contains an enormous area from Nero's villa. It was restored at great expense in the 1980s and 1990s, opened to the public, and then closed again after a few years when it began to leak!

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 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

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.

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).

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.

Located a short walk west of the Colosseum, this well-preserved monumental arch was erected (soon after 315) to commemorate the victory of Constantine, the first Christian emperor, over his rival Maxentius at the Battle of the Milvian Bridge in 312. In general design, the Arch of Constantine imitates the century-earlier Arch of Septimius Severus (nearby in the Forum). The three arches are decorated utilizing mainly materials plundered from other imperial monuments by Trajan, Hadrian and Marcus Aurelius. The quality of its sculptural decoration, however, betrays the slow degradation that Classical Roman sculpture had experienced in the 3rd century AD.

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.
