The Pontifical Swiss Guard is a group known for standing guard at the entrances to Vatican City. Their main job is to provide security and protect the Pope. They can easily be recognized by their distinctive uniforms, which are very colorful and look much like the clothing worn by soldiers during the Renaissance era.
The Pontifical Swiss Guard holds the title of being the smallest and oldest standing army in the world. This tradition began in 1506 when Pope Julius II officially founded the Guard. However, the use of Swiss soldiers by the popes dates back even further. During the 1400s, Swiss mercenaries were often brought to Rome to serve as bodyguards for the pope and to provide extra security.

This palace of the 16th century was erected by the famous Medici family. It was the residence of Cardinals Giovanni and Giuliano Medici, later Pope Leo X. and Clement VII. Catherine de Medici, Pope Clement VII's niece lived here until her marriage in 1553 with Prince Henry, the son of King Francis I of France. The palace is named after Madama Margerita of Austria, the illegitimate daughter of Emperor Charles V. Since 1871 it has been the seat of the Italian Senate.
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.
Built in 141 AD and dedicated to the Empress Faustina; after her husband emperor Antoninus Pius died in 161 AD the temple was rededicated to the couple.
An underrated way to see fantastic art made after the Renaissance. Mainly Italian artists, notably De Chirico, but Cézanne, Degas, Kandinsky, Man Ray, Modigliani, Monet, Pollock and Van Gogh are also represented.
Between the Pantheon and Via del Corso. A stunning example of Baroque art. The ceiling frescoes are especially fine, including a trompe l'oeil dome by the master Andrea Pozzo.
The most extensive collection of Etruscan art and artifacts anywhere. Fantastic collection and well worth the admission charge. A difficult museum to find, but a lovely display in a beautiful villa setting.
Brand new museum designed to celebrate the art and architecture of the 21st century.
The remains of the ancient Roman archives, where Cicero and Seneca did research. Visible from the Forum and accessible through the Capitoline 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 building housed the University of Rome from the middle of the 15th century until 1935. The splendid interior courtyard was created by Giacomo della Porta. The inside church of Sant'Ivo (see above) is one of the masterpieces of the architect Borromini.
Next door to the Pyramid, this fine gate in the Aurelian Wall is named after St. Paul as the Via Ostiense leads to the basilica of St. Paul's Outside the Walls (see Rome/South).
The 4th rebuilding of the meeting place for the Roman Senate, once converted into a church during the Middle Ages, but now restored since the 1930s.
Good collection of Renaissance and Baroque art, including by Velasquez, Titian, Raphael, and Bernini, all owned by the Doria Pamphilj family. Excellent audio guides really bring the paintings to life.
At the southern end of the Piazza, designed by Bernini but the main statue of the Moor was done by Giacomo della Porta and the other statues are 19th-century copies of the originals.
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.
