Trajan's bridge over the Danube

The band of relief sculptures on the Column of Trajan in Rome depicts Emperor Trajan with his master builder Apollodorus and soldiers presenting an offering before the wooden bridge over the Danube. Trajan had the bridge constructed in 103-105 AD at Drobety, the modern-day Turnu-Severin in Romania. This permanent passage over the Danube was of great military importance during the campaigns in Dacia. Some of the 20 stone pillars supporting the wooden bridge, which measured approx. 1,000 metres in length, can still be seen today.
