Trajan's Column was erected by the Senate in 113AD to commemorate Emperor Trajan's campaigns against the Dacians
(modern day Romania)
An inscription above the door at the base records that the height of the column corresponded to the height of the hill which it replaced.
The column is made up of 19 drums of Italian marble covered in reliefs. These scenes tell us so much about the Roman army, for example, you can see that the helmets have small rings on top so that they could be hung from a cord over the shoulder when they were not worn.
Finally, a good place to eat with a great view of the column is Terre e Domus (formally Enoteca Provincia Romana). The ingredients for the traditional Roman dishes are all sourced locally and the project is managed by a social co-operative.
