Seuthopolis

Seuthopolis (Ancient Greek: Σευθόπολις) was an ancient Hellenistic city founded by the Thracian king Seuthes III between 325–315 BC which was the capital of the Odrysian kingdom. Its ruins are now located at the bottom of the Koprinka Reservoir near Kazanlak, Stara Zagora Province, in central Bulgaria. Several kilometres north of the city is the Valley of the Thracian Rulers, where many Thracian royal tombs are located.
