The Trajan column was built in AD 113 to remind Roman citizens of the two military victories of the Roman Emperor Trajan in the Dacia war, now modern Romania. The stunning engraving reliefs that rotate around the pillars reproduce Dacia's activities, including Trajan's own, resolving the troops, leading the army, rewarding support staff and judging prisoners. The column still stands in the heart of modern Rome and is one of the most respected monuments in the Roman world.
