Serbian archaeologists have discovered the remains of about 9,000 year-old settlement in the east of the country in 2005. The site is located in an inaccessible cave above the Danube. Until now, remains of fireplaces and flat stones that were used as anvils been excavated. In addition, numerous bones were found of fish and other animals.

Roman Ruins

A well-known Roman Fund is the rock-cut the Iron Gate Tabula Traiana on the Serbian side of the Danube. It is a panel that made Attach the occasion of the completion of road construction in the lower gorge of the Danube, the Roman Emperor Trajan in the year 100. On both sides of the panel doppeltgeränderten floating dolphins are shown above hovers an eagle with open wings, right and left are three sechsblätterige roses carved in relief in the stone. In the construction of the power plant, the panel was offset to get them. Today, it is only visible from the water.

In the years 102 to 105 of the important Roman architect Apollodorus of Damascus, built in Drobeta Turnu Severin Taldurchbruch at the Trajan and prolonged by a strategically important Roman road across the former border river beyond. The bridge, which was the longest of the ancient world, was soon used for the invasion of Dacia during the Second Dakerkrieg 105/106. With the annexation of Dacia as a Roman province the frontier of the Roman Empire was pushed across the Danube.

Regulation in the 1890s

Already in the 1830s first rock blasting were carried out to improve the fairway on behalf of Austria. At the Berlin Congress of 1878 Austria - Hungary had been entrusted with the regulation of the Danube at the Iron Gates route. The Hungarian government allowed the construction work to perform under the direction of Ernst Wallandts in the years 1890-1896 with high costs and overcoming major technical difficulties. The regulated stretch of the Danube at the Iron Gate was opened by emperor Franz Joseph I of Austria on 27 September 1896. Present were also the neighboring sovereigns, the kings of Serbia and Romania.

The regulation works consisted of an almost 8 km long, 3 m reaching below the lowest level of the level of channel through the rapids on the Serbia -facing side of the Danube. The channel was divided into two parts, one about 6 km long, extending into the area of Kazanfelsenge ( the Turkish word Kazan means cooking kettle ) leading gutter under water, which is marked by buoys, and an approximately 1700 m long outcropping lower part, the 12 m high embankments was edged out of rock blocks to 150 m wide. To prepare the upper channel portion had 253,000, 400,000 m³ of the lower rocks are blown up. However, the high flow speed in this " Iron Gate channel" or in Serbian " Sip - channel " hampered the ascent of that steamships considerable, so that there two tugs were deployed to the bias power.


Until the 1960s, a built in World War Treidelbahn was operated on Yugoslavian, right bank of the Danube. This railway line is not connected to the European railway network was used to pull cargo ships upstream.
