Built between 106 and 113 A.D., it is covered with reliefs depicting 155 scenes with 2,662 figures, among which the emperor himself appears 58 times.
After its construction, a sculpture of an eagle was placed on the column, which was replaced by a statue of Trajan after the emperor's death. This statue towered over the area for almost a millennium and a half.
On December 4, 1587, a bronze statue of St. Peter the Apostle was placed on the column. This act was initiated by Pope Sixtus V. The statue adorns the column to this day.
