Ara Pacis is an altar to peace commissioned by the Roman Senate on 4 July 13 BC to honor the triumphal return from Hispania and Gaul of Augustus. It is universally recognised as a masterpiece. Following discovery of this work under a building in Rome, Mussolini built a protective building for it near the Mausoleum of Augustus, where it was reconstructed. A new building on the same site as Mussolini's was opened in 2006 and has been controversial. The mayor at the time said he would tear down the new structure. The basement of the new building features occasional exhibitions. You can see much of it from outside the building. Paying to go inside adds some background info, but not much more.

This was the site of the slaughter in 1944 of 335 Italians, including many Jews from the Ghetto, in retaliation for a Partisan attack on German troops in Rome. The caves where the massacre took place are now a National Monument and Memorial Cemetery and can be visited daily.

If it is sunny, you'll catch a few young people and older gentlemen sitting at the base of a statue in the middle of the open space. The statue is a brooding, hooded Giordano Bruno—an excommunicated Dominican monk and one of the earliest cosmologists who held the idea of an infinite universe. He was burnt at the stake for heresy on this spot on 17 February 1600. The piazza is used as a marketplace during the day, and party central for college students and tourists at night. When the sky gets dark and the street lamps go on, the Campo de' Fiori fills with people and lovers wander arm in arm in the crowd. Over the buzzing of conversation and the occasional burst of laughter you may hear a young vocalist belt out O Sole Mio at the top of his lungs as change plunks into his accordion case.

An ancient Egyptian obelisk brought to Rome in 10 BC.

By Borromini, reputed to be on the spot where St. Agnes was martyred in the 4th century AD. This lovely basilica church is small with an almost circular interior. It is undergoing rehabilitation and the facade and dome are hidden in scaffolding. It seems to be open only until noon.

Small and attractive piazza tucked away in a neighborhood near Pantheon.

Known properly as the Flavian Amphitheatre, this most famous of Roman landmarks takes its name from the giant statue of the emperor Nero that once stood near this location. The amphitheatre was capable of seating 50,000 spectators for animal fights and gladiatorial combats. It was a project started by the Emperor Vespasian in 72 and completed by his son Domitian sometime in the 80s. The Colosseum when completed measured 48 m high, 188 m in length, and 156 m in width. The wooden arena floor was 86 m by 54 m, and covered by sand.;Expect a long queue and an even longer wait. You can skip the queue if you decide to take a tour, but if you don't want a tour, you can STILL skip the queue. If you walk to the entrance for the Roman Forum, you can buy tickets there which allow you to bypass the queues. You can also buy tickets online. There are lots of people offering tours in English just outside the entrance to the Colosseum. Inside you can take a tour (English, Spanish, or German) every 30 minutes or so for an additional fee. The tours are given by knowledgeable archeologists, but they don't take you to any areas you couldn't visit on your own.

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.

The palace was built by the architect Baldassare Peruzzi on behalf of the Massimo family. The former palace was destroyed during the pillage of Rome in 1527. The Massimo family can be traced back to Quintus Fabius Maximus who defeated Hannibal in the 3rd century BC. The building is open to the public on March 16, only in order to commemorate the miraculous reanimation of Paolo Massimo by St. Philip Neri in 1538.

The highest hill in Rome at 139 m, with sweeping views of the Vatican and Rome across the Tiber.

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.

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.
