The Roman Ghetto is located between the island in the River Tiber and the Theatre of Marcellus, and today it is home to Rome’s synagogue. This historic district was established in 1555 when Pope Paul IV issued a Papal Bull that required all Jews in Rome to live within its borders. At the time, the area was considered undesirable, as it suffered from frequent flooding by the nearby river.
When the Ghetto was created, it was enclosed by walls and gates. These gates were only open during the day, which confined the Jewish residents to the area at night. Life was challenging for those living inside the Ghetto, as the community faced many restrictions and hardships over the centuries.
The conditions changed dramatically with the end of the Papal States in 1870. The rule requiring Jews to live within the Ghetto ended, and eighteen years later, the physical walls surrounding the area were removed. Much of the original Ghetto was demolished during this period, but traces of its history remain.
Today, visitors can still find evidence of the past in the Roman Ghetto. Some buildings preserve pieces of ancient Roman ruins in their walls, offering a glimpse into the layered history of the neighborhood. The area is also known for its Jewish restaurants, which serve traditional dishes and keep the spirit of the community alive in the heart of Rome.

This church, which was commissioned by Ferdinand and Isabella of Spain, marks the point where, according to tradition, St. Peter was crucified. Particularly interesting for Irish visitors as it contains the graves of three Gaelic Chiefs who fled Ireland in 1607.
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.
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.
A truly monumental stairway of 135 steps (similar to climbing eight flights of stairs), built with French funds between 1721 and 1725 in order to link the Bourbon Spanish embassy to the Holy See (still located in the piazza below), with the Bourbon French church (its monastery founded in 1495) above. Don't sit on them though, or eat, or push a baby stroller on them, or do anything else that might obstruct pedestrians, make them dirty, or cause additional wear and tear, or else you will have to pay a fine that ranges from €250 to €400.
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.
Rome's museum of contemporary art, housed in a former industrial complex. Rotating exhibitions, each one usually lasting about 4 months. The MACRO Testaccio exhibition space is located in Aventino-Testaccio.
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.
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
The renamed Rome Zoo, one of the oldest in Europe, founded in 1911. On the edge of the Borghese Gardens, a short, well-signposted walk from the Gallery. They try hard, but San Diego this isn't. If you are a regular zoo-goer you will be disappointed.
A very ancient church named after a saint who was in 1969 removed from the Roman Catholic calendar of saints for the lack of details of her life. But the church retains the name and is well worth visiting for an excellent 4th-century mosaic and attractive decorations on the facade. Visiting hours are short, but if you arrive close to 11:30, try talking to the attendant if you see him, and he might let you visit for a few minutes. The church is small, so 15 minutes should be long enough to see and absorb everything.
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.
