The location of the Kabyle was very important, which is the reason the town was repeatedly attacked and conquered. In 342/341 BC. Philip II conquered it. Here is situated a military garrison and town was built in the architectural principles of Hellenism.
72 BC the city was conquered and destroyed by Marc Terentsiy Varon Lucullus as a punitive action because of the participation of the Thracians as allies of Mithridates VI Yevpatoriya against Rome.
Kabyle reached its apogee in II - III century when it became the most important Roman military camp in the province of Thrace and a major crossroad junction.
At the end of VI century the city was conquered and destroyed by Avars.
In 1965 the site was declared an archaeological reserve and now is one of the 100 national tourist sites of Bulgaria.
