It was a significant economic and military centre of the Dacian Suci tribe.
The Roman fort, one of the largest Roman forts in Oltenia, was built over the former Dacian citadel in the 270s[4] at the time of Roman withdrawal from Dacia to protect the Roman pontoon bridge and road there. The defensive walls with eight towers of the late Roman town of Sucidava can still be seen.
Constantine's Bridge (Danube) was built nearby over the Danube in 328 in order to start his reconquest of Dacia. Sucidava had its own defensive walls protecting the city and the bridge. The bridge connected to the Oescus fort in Bulgaria which protected its southern end.
The city developed around the fort. The archaeological evidence shows that in 443–447 the city and the fort were sacked by the Huns, and were restored under Justin I 518–527 or Justinian I 527–565.[5] Around 600, it seems that the Roman garrison abandoned the city.[2][dead link]
The first ChristianBasilica established in Romania can be found there. There is also a secret underground fountain which flows under the walls of the town to a water spring situated outside.
