Noviodunum, known also as Noviodunum ad Istrum, was a fort and a port in the Roman province of Moesia located on the lower Danube.
The geographical position of this settlement offered to the Romans the possibility of supervision and control of the border of the entire Roman limes in the north of the Danube. The strategic importance has been determinant in the economic and administrative function around which developed the military and naval legionaries.
Noviodunum was passed under Roman control with the annexation of Thrace in 46 AD, being then attached to the Roman province of Moesia.
It became an important port of Classis Flavia Moesica and a military center of the region starting from Domitian-Trajan, after the conquest of Dacia. Here some vexillationes of legio V Macedonica were detached, at least until the reign of Marcus Aurelius. Then followed vexillationes of legio I Italica, and then from the Diocletian legio I Iovia.
It was probably destroyed during the second half of the 3rd century during the period of heavy invasions of Goths and Heruli. It was rebuilt during the reign of Emperor Constantine the Great (after 324), during the military campaigns and placed under the command of Dux Scythiae. In 369 on the opposite bank of the Danube was fought a great battle between the Emperor Valens and Athanaric and its Tervingi.
