Tre Fontane Abbey

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.

Romans and leaders of Rome's defeated enemies were imprisoned here where they either died of starvation or strangulation. According to legend, St. Peter was also imprisoned here.

The two museums are on opposite sides of the Piazza del Campidoglio, It is recommended to book tickets online 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). 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.

They are posted at entrances to the Vatican City to provide security and protect the Pope. They wear very colourful clothing, similar to the uniforms worn by Renaissance-era soldiers. The Pontifical Swiss Guards is also the smallest and oldest standing army in the world, founded in 1506 by Pope Julius II. The origins of the Swiss guards, however, go back much further as the popes had regularly imported Swiss mercenaries during the 1400s.

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.

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.

This little church is hard to find but well worth the extra effort although it is often closed when you get there. One of Borromini's masterpieces. It is located only a block from Piazza Navona, but not usually visible from the street, as you must enter the courtyard of an old palazzo to reach the church. Sant'Ivo is a small church the dome of which is shaped like the Star of David, but with every other point rounded. The steeple seen from the outside looks like it has a staircase wrapped around it that ascends to heaven. As the church was commissioned by the Barberini family that produced a number of popes and whose family symbol was the bee—some say the steeple resembles the stinger of the insect.

The Ghetto lies between the island in the River Tiber and the Theatre of Marcellus and includes Rome’s synagogue. It was established in 1555 as a result of a Papal Bull by Pope Paul IV that required all Jews to live in the area, considered one of the least desirable quarters of the city, as it was subject to constant flooding by the river. The area was originally enclosed by walls and gates that were only open during the day. With the end of the Papal States in 1870, the requirement that Jews live in the Ghetto came to an end. The walls were torn down in 1888 and much of the ghetto was demolished. However, there is still much to see, including walls of buildings that incorporate Roman ruins, and there are several good Jewish restaurants.

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.

In the Middle Ages pilgrims on their way to St. Peter's had to pass through the Via dei Coronari in order to cross the Tiber at Ponte St. Angelo. The street got its name from the people who sold rosaries to the pilgrims. It follows the ancient Via Recta which led from what is today Piazza Colonna to the Tiber. In the 15th century Pope Sixtus IV initiated the construction of private buildings. Today, several houses dating back to the 15th and 16th century may be seen. House nr. 156/157 is said to have been the House of Fiametta, the mistress of Cesare Borgia.

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.

More of an enormous traffic circle than a piazza, but a good central location. The centerpiece is the enormous Vittorio Emanuele Monument (aka the Wedding Cake or the Typewriter) with the Capitoline hill next door. Mussolini used to harangue Romans from the first floor balcony of Palazzo Venezia (see under Museums), to the west of the square.

This impressive villa covers 23 hectares. It can be accessed from the Via Appia Nuova (Bus 118) or through Via Appia Antica 251. Parts can be seen from the Appian Way at around the 5th mile just after No 251. The villa was built by Maximus and Condinus Quintilii. The emperor Commudus liked it so much that he put the brothers to death in 182 AD and took it for himself. A museum has friezes and sculptures from the villa. The nypheum, the tepidarium and the baths may also be visited. At Appia Antica 251 is Santa Maria Nova, a farmhouse that has undergone many reincarnations since being built on top of a Roman cistern that was probably used by Villa dei Quintilii.

The house in which the famous English poet John Keats succumbed to consumption, now preserved as a memorial to his life and that of his friend Shelley, both of whom are buried in Rome's Protestant Cemetery (see Testaccio).

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.
