Santa Passera

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.

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

Regular shows plus an excellent astronomical museum.

It was constructed to hold relics of the Passion of Jesus. They include two thorns of his crown, part of a nail and three small wooden pieces of the Cross. The authenticity of these relics is much disputed, however.

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 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.

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.

On the site of the Roman baths, this museum houses an enormous collection of statues, etc.

This is a treasure-trove of art. There are a couple of paintings by Caravaggio: "The Crucifixion of Saint Peter" and "The Conversion of Saint Paul" (in a dim alcove to the left of the altar, both at right angles to the viewer, with a machine wanting €2 to switch on the lighting) together with a sculpture by Bernini, frescoes by Pinturicchio and mosaics by Raphael. Part of the Dan Brown tour, this church featured in Angels and Demons, although the Vatican did not allow filming inside.

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.

Perhaps the most fascinating building in Rome. The core of the structure began life as the mausoleum of Emperor Hadrian, built between 135 and 139 AD. Subsequent strongholds built on top of the mausoleum were in turn incorporated into a residence and castle by medieval Popes. The building was used as a prison until 1870 but now houses a museum. Opera buffs will be exhilarated to visit the balcony from which Tosca leaps to her death. Film buffs will recognise it as a setting from Angels and Demons.

This is the largest square in Rome. It sometimes hosts pop concerts and is the focal point for Rome's New Year's Eve celebrations. The twin churches Santa Maria dei Miracoli (1681) and Santa Maria in Montesanto (1679) used to provide a clear welcome to Rome for those coming from the north. Much older, to the north of the piazza is yet another Santa Maria (see below). The Piazza del Popolo is considered as one of the most beautiful squares in Europe. It was enlarged and two streets, the Via di Ripetta and the Via del Babuino were added by order of Pope Sixtus V. In the middle of the square is an obelisk (see below). In 1809-1816, Giuseppe Valadier, Roman architect of French origin, gave the square its characteristic oval shape.

A lovely, if somewhat run-down park (parts of it are blocked due to the poor state of the roads) with statues and a great view on the city.

An example of urban planning that goes back to Pope Julius II, who, in 1508, envisioned it as a street that would connect all major government buildings. It is around a kilometer long and is in a straight line, an unusual feature for the time. It is lined with some interesting palaces but these days is more known for its antique shops. Via Giulia runs parallel with and one block from the River Tiber.

The Celian Hill is one of the seven hills of Rome. You immediately see the church of San Gregorio Magno. On this site monks were trained before setting off as missionaries to England at the end of the 6th Century. Further up the hill is Santi Giovanni e Paolo. At this point it is difficult to believe you are in the middle of a major city. This church was built in 398 over the home of two Roman soldiers, John and Paul, who were martyred for their Christian beliefs in 362. Excavations show that there were several burials on the site, a risky business as burials were illegal at that time. After the church you come to the back entrance of the Villa Celimontana park (jazz festival nightly in late June-August). The modern buildings before you reach the park are owned by Silvio Berlusconi’s television company. By the main entrance of the park note the boat-like fountain known as the “Navicella”. As you exit the main entrance to the left is the church of S. Maria in Domnica, which has some interesting mosaics. Next to this church is the Porta Esquilina, one of the gates from the original Servian walls of Rome. It dates back to the 4th century BC.
