Trajan's Column is a Roman triumphal column in Rome, Italy, that commemorates Roman emperor Trajan's victory in the Dacian Wars. It was probably constructed under the supervision of the architect Apollodorus of Damascus at the order of the Roman Senate. It is located in Trajan's Forum, north of the Roman Forum.

The most famous "pillar" in Rome is Trajan's Column (Colonna Traiana), located in Trajan's Forum near the Piazza Venezia. Completed in 113 AD, this 38-meter tall triumphal monument is renowned for its intricate spiral frieze that winds around the shaft 23 times. The carvings act like an "ancient movie," depicting the Roman Emperor Trajan’s victorious military campaigns in Dacia (modern-day Romania) in stunning detail, featuring over 2,500 individual figures. The column is made of 20 massive blocks of Carrara marble, and inside, a hidden spiral staircase leads to a viewing platform at the top (though this is rarely open to the public). Historically, it also served as Trajan's tomb, as his ashes were placed in a golden urn in the base. It has stood for nearly 2,000 years as one of the best-preserved examples of Roman imperial propaganda and a masterpiece of ancient engineering and narrative art.
