Nicopolis ad Istrum - A settlement in Moesia
Nicopolis ad Istrum was a Roman and Early Byzantine town founded by Emperor Trajan around 101–106, at the junction of the Iatrus (Yantra) and the Rositsa rivers, in memory of his victory over the Dacians. Its ruins are located at the village of Nikyup.

The classical town was planned according to the orthogonal system. The network of streets, the forum surrounded by an Ionic colonnade and many buildings, a two-nave room later turned into a basilica and other public buildings have been uncovered. The rich architectures and sculptures show a similarity with those of the ancient towns in Asia Minor. Nicopolis ad Istrum had issued coins, bearing images of its own public buildings.

In 447, the town was destroyed by Attila's Huns. In the 6th century, it was rebuilt as a powerful fortress enclosing little more than military buildings and churches, following a very common trend for the cities of that century in the Danube area.
