The "big column" most people refer to in Rome is Trajan's Column, located in Trajan's Forum near the Piazza Venezia. Completed in AD 113, this triumphal monument stands roughly 30 meters (98 feet) high—115 feet including the large pedestal. It is most famous for its intricate, spiraling "low relief" frieze that winds around the shaft 23 times, depicting the Roman emperor Trajan's two victorious military campaigns against the Dacians (modern-day Romania). The frieze features more than 2,500 individual figures and provides historians with a "stone documentary" of Roman military equipment, engineering, and daily life. Inside the column is a spiral staircase leading to a viewing platform at the top, which originally held a bronze statue of Trajan, though it was replaced by a statue of St. Peter in 1587. Another notable "big column" in Rome is the Column of Marcus Aurelius in Piazza Colonna, built later in the 2nd century, which follows a similar spiraling narrative design.
