They made roads on the left and the right bank, which supposed to allow the passage of legionaries to march to the Dacia (present-day Romania). Many Roman emperors were involved in the regulation of the Iron Gate, starting from Julius Caesar, but the best known Traian, conqueror of Dacia, who managed to secure passage through the gorge. During his reign the walls of the right bank of the Danube were carved and the first bridge was built across the Danube river between Turnu-Severin and Kostol.
