During the time of Emperor Diocletian or Constantine I the Great (late III or early IV c.)  a castle was built on the banks of the Danube to strengthen the defense of the Danube limes. It is likely that it was destroyed in the middle of the V c. during the Huns invasions. Later, in the VI c., during the large-scale construction program of Emperor Justinian I the Great, a new massive fortress wall was erected which was rebuilt and used until the beginning of the XIX century.

It is one of the most powerful military defense equipment unmatched in late antiquity. It was built of three rows of large stone blocks and bricks above them. The fortress is impressive with the fact that dense triangular and pentagonal towers alternate on the east, west and south walls in 12 m. In front of the northern fortress wall was the port of the late antique and medieval city.
