ARCHAEOLOGICAL EXPLORATIONS ON KOZI GRAMADI PEAK (Ivan Hristov – ivchristov70@abv.bg) The Thracian residence covered an area of 0.34 ha. The main tower-gate was discovered in the southeastern part of the fortification, in the middle of the first fortification wall. The tower-gate was 6 m by 5.95 m in size and was built of granite ashlars with an entrance to the northeast, 2.30 m wide. In a later period, the entrance of the tower-gate was closed with roughly cut stones bonded with mud. The first southeastern fortification wall was built in polygonal opus emplectum with roughly cut ashlars. The area between both fortification walls was explored, where the residential part of the fortification was situated. Several rooms arranged in a line along the outer face of the second fortification wall were discovered. Their walls were constructed with sun-dried bricks and their roofs were covered with Corinthian tegulae. A street was documented to the north of the second fortification wall and a yard, 300 sq. m in size and situated to the east of the main residence building, was explored. Six cisterns, pits for dolia, Corinthian tegulae and Laconian imbrices were discovered to the northeast of the main residence building. The northeastern wall of the main residence building, situated in the center of the complex with an entrance to the southeast, was discovered. The wall was 13 m long and preserved over 2 m in height. The finds included Corinthian tegulae, Laconian imbrices, sherds, including from imported Greek amphorae and black-gloss pottery. The residence functioned during the first half of the 4th century BC.
