Trajan’s Column is the only monument in the Roman Forum that has reached us practically intact. The column, together with its base, reaches to a height of almost 40m and is an indication of the original height of the ‘saddle’ of the Quirinal Hill, which was cut into to build Trajan’s Forum.
The extraordinary reliefs that cover Trajan’s Column, forming a spiral of almost 200m in portray the victorious military campaigns led by Trajan against the Dacians; conflicts that made the borders on the Danube secure. There are around 2,500 carved figures. On the base are carved trophies of arms and there is a small door behind which a burial chamber once contained an urn with the ashes of Trajan.
