Abstract: The authors aimed to present the evolution in time of the main arrangements made in the Iron Gates area. The engineer works during the emperor Trajan’s epoch are shortly presented; they have been taken back only in the 19th century, at the initiative of the Austria-Hungary. The originality is represented by the mentioning of two diplomatic documents discovered in the Romanian and Italian archives, which refer to this particular moment, considered to have great importance for the region.
