Residences and temples of the Odrysian kingdom have been found, particularly around Starosel in the Sredna Gora mountains. Archaeologists have uncovered the northeastern wall of the Thracian kings' residence, 13 m in length and preserved up to 2 m in height. They also found the names of Cleobulus and Anaxandros, Philip II of Macedon's generals who led the assault on the Odrysian kingdom.
