Portile de Fier. The Iron Gates
The Danube, on a part between Romania and Serbia, makes an espectacular canyon caled the Iron Gates. The gates begin in Bazias and finish in Dobreta Turnu Severin, the capital of the Mehedinta Judet (district). The whole distance of the canyon is about 135 kms. The zone is divided onto three parts, I have only visited the final part, from Orsova to Dobreta, where the dam is, making the pass of the frontier between Serbia and Romania.
I have attached photos from the city of Dobreta, with roman history on their pilars, never batter said, cause it was the place where Traian cross the Danube from Serbia to Romania, to conquer Dacia (nowadays Romania) and he stopped the Dacian invasions on the roman province of Moesia (now it crompises parts of Bulgaria and Serbia), leaded by the famous dacian, Decebal.
I found there, in the city, the pilars of the bridge. Those are only the ruins that left from it (and as well in the serbian side)
