KOTOR- Old Historical Town - Montenegro Royalty-Free Stock Image

The town has been fortified since the early Middle Ages, when Emperor Justinian built a fortress above Ascrivium in 535, after expelling the Ostrogoths. Ascrivium was plundered by the Saracens in 840. It was further fortified towards the peak of Saint Ivan by Constantine VII Porphyrogennetos in the 10th century. It was one of the more influential Dalmatian city-states of romanized Illyrians throughout the early Middle Ages, and until the 11th century the Dalmatian language was still spoken in Kotor. The city was part of Byzantine Dalmatia in that period, and the modern name of Kotor probably originated in the Byzantine name for the town: Dekatera or Dekaderon.
