This column, located in Trajan's Forum, commemorates the Roman emperor Trajan and his victories in Dacian Wars. It was erected in 113 AD and has inspired many victorious columns scattered around the world since then.
The column is topped with the statue of St. Peter. However, the most imposing features of the structure are the spiral reliefs that tell the tale of the Dacian wars. The images are done in great detail and are definitely worth noticing.
After his death, Trajan's ashes were stored in the chamber under the column but they were eventually removed.
The column is hollow and there is a staircase inside that leads all the way to the top of it. Sadly, it is not open to the public.
