Perperikon

Perperek is a complex with remains from early history, antiquity and the Middle Ages in Bulgaria's Eastern Rhodope Mountains. It includes a large megalithic sanctuary, ancient monuments and a medieval fortress. The complex lies 15 km northeast of Kardzhali and occupies the highest peak in the area.

The name "Perperek" is Thracian and is associated with the meaning "rock". In Thracian tradition, the complex is regarded as a sacred rock city, a capital and a fortress with a royal palace. Thracians, Romans, Goths, Byzantines and Bulgarians lived here at different times.

The megalithic complex at Perperek is the largest on the Balkan Peninsula, covering 5,000 square metres. The Thracian sanctuary stands 470 metres above sea level. The complex was declared a cultural heritage monument of national significance in 1968.

Bulgarian historical scholarship began discovering and studying Perperek in 1931, and it became a subject of research for archaeologists and historians. Its history and significance were included in Bulgarian school curricula in 1938.

The site is listed as one of Bulgaria's Hundred National Tourist Sites.
