Trajan's Column, constructed by the architect Apollodorus of Damascus, and completed in AD 113, at the order of the Roman Senate, is located in Trajan's Forum near the Quirinal Hill to the north of the Roman Forum.

The structure is about 30 metres (98 ft) in height, 38 metres (125 ft) including its large pedestal. The shaft is made from a series of 20 colossal Carrara marble drums, each weighing about 40 tons, with a diameter of about 4 meters (13 ft).
