Bulgarian archaeologists have made crucial discoveries at the residence of the rulers of the Odrysian Kingdom, the state of the most powerful tribe of Ancient Thrace, including details about its sacking by the troops of Philip II of Macedon.
The discoveries have been made within the project of Bulgaria's National History Museum, whose team started in early June 2011 the largest alpine expedition in the history of Bulgarian archaeology
in order to excavate the residence of the rulers of the Odrysian Kingdom.
Bulgarian archaeologists uncovered the unique residence of the rulers of the Odrysian Kingdom in July 2010, after its location was initially detected in 2005.
The residence is located on the Kozi Gramadi mount in the Sredna Gora mountain, in the village of Starosel, close to the resort town of Hissar in central Bulgaria, at about 1 200 m above sea level.
The National History Museum announced Tuesday that its archaeologists have uncovered in full the northeastern wall of the Thracian kings' residence; it is 13 m long, and has been preserved at a height of 2 m, according to the head of the expedition, Prof. Ivan Hristov.
Not unlike the facade of the building uncovered in 2005, the northeastern wall is made with "perfectly prepared stone blocks with encarved decorations." The building is believed to have hosted the treasury of the Odrysian rulers. It was erected by Ancient Greek architects between 354 BC and 342 BC, which is also when the Thracian kings' residence is dated, during the rule of Odrysian king Teres II (351 BC-341 BC).
