Summary (English)

  • EXPLORATIONS IN SOZOPOLIS (Tsonya Drazheva – The newly discovered section from the fortification wall, situated between both towers, was 24 m long. The wall was 1.80 m wide and preserved up to 3.80 m in height. It was built of ashlars (including spolia: reused ashlars and marble architectural details) bonded with mortar with an emplectum of uneven stones bonded with mortar. The foundation was 20 – 40 cm deep and was constructed over the cutout bedrock. The exploration of rectangular Tower No. 2, 7 m by 8.20 m in size, continued in the southeastern part of the fortification wall. The walls of the tower were 1.20 m wide, built of ashlars and preserved up to 3.20 m in height. The fortification wall and Tower No. 2 were built at the end of the 4th – beginning of the 5th century AD. At the end of the 5th century AD reconstructions of the fortification wall were done and Tower No. 1 was additionally built, in order to strengthen the western side. The finds included sherds from amphorae and pottery from the 4th to the 17th centuries, a Byzantine anonymous follis of the 11th century and a silver grosso of Bulgarian King Ivan Shishman (1371 – 1395). Three kilns, constructed of stones and partly dug into the bedrock, were explored in front and to the south of the fortification wall. Kiln No. 1 was beehive, 1.40 m by 1.50 m in size, with a prefurnium, 70 cm long and 32 cm deep. The kiln was filled with lime. Apparently, the kiln was used for firing limestone to produce lime which was used for the construction of the fortification wall. Kiln No. 2 was circular, 70 cm in diameter. Kiln No. 3 was ellipsoid, 80 cm by 90 cm in size. Sherds and two bronze coins of Apollonia of the 3rd – 2nd century BC were found in the interior of kilns Nos. 2 and 3 and in the layer between them. Iron mill-bar and slag were found close to kiln No. 3 and they indicated that both kilns were metallurgical. The cultural layer around the kilns was destroyed during the construction of the fortification wall and by two graves of the 5th – 6th centuries AD.
