In the historic center of Rome, Piazza Colonna stands out as a place where political life and ancient history come together. This lively square is home to Palazzo Chigi, the official residence of the Italian Prime Minister. The dignified facade of Palazzo Chigi forms an important backdrop to the daily activity that fills the area.
The square takes its name from an impressive column, the Colonna di Marco Aurelio, which rises in the middle of the piazza. This carved monument dates all the way back to the days of Imperial Rome. Each intricate relief tells parts of ancient stories, offering visitors a glimpse into the city’s proud past. The column remains one of the most striking features of the area, drawing attention from those passing through as well as anyone interested in Roman history and art.
