The Ancient Thracian city of Kabile is a nowadays Archaeological Preserve located 10 km away for the southeastern Bulgarian city of Yambol. The city of Kabile was founded around 2000 BC, and was one of the most important cities of Ancient Thrace. In fact, it is believed to have been one of the royal residences of the kings from the Odryssian Kingdom, the most powerful state of the Ancient Thracians. In 341 BC, Kabile was conquered by Philip II of Macedon. The Ancient Thracian city is mentioned by 14 ancient authors, the first of whom describes its conquest by Philip II of Macedon.
After the collapse of Alexander the Great’s empire, in the 3rd century BC, Kabile was ruled once again by the Ancient Thracians. It was conquered by the Roman Empire in 71 BC, and later was incorporated into the Roman province of Thrace. It was an important regional center in the Late Antiquity as well. The city of Kabile was modeled after the Ancient Greek cities at the time. It boasts a stone acropolis with a unique rock relief of the ancient goddess of Cybele, a protector of the city.
In the 4th century AD, Kabile was conquered by the Goths, and was later destroyed for good by the Avars. The Kabile Archaeological Reserve was established in 1965 on a territory of 650 decares (160 acres). It features ancient structures such as the agora (a central square), Roman barracks, Roman thermae, a bishop’s basilica, among others. Kabile is excavated every year by archaeological teams from Bulgaria and abroad.
