Where the building of the Italian Government, Palazzo Chigi is situated. Also there is a marvelous carved column—hence the name—dating back to Imperial Rome.
Piazza Colonna is a piazza at the center of the Rione of Colonna in the historic heart of Rome, Italy. It is named for the marble Column of Marcus Aurelius, which has stood there since AD 193. The bronze statue of Saint Paul that crowns the column was placed in 1589, by order of Pope Sixtus V. The Roman Via Lata runs through the piazza's eastern end, from south to north.

Montecitorio Obelisk
An ancient Egyptian obelisk brought to Rome in 10 BC.
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).
Small and attractive piazza tucked away in a neighborhood near Pantheon.
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.
