Tabula Traiana

The Tabula Traiana or Trajan's Plaque is a Roman memorial plaque found on the Serbian side of the Iron Gates of the Danube. The plaque was erected by Roman Emperor Trajan to commemorate the completion of his military road along the Danube. It was declared a Monument of Culture of Exceptional Importance in 1979, and is protected by the Republic of Serbia.

The plaque and the accompanying Roman road were constructed between AD 98 and 100. At its peak, the road was a marvel of engineering, partially carved into the cliff faces and supported by a wooden scaffold over the water. The monument was relocated in 1972 when the Iron Gate I Hydroelectric Power Station was built, raising the water level of the Danube by about 35 meters.
