ARCHAEOLOGICAL EXPLORATIONS OF HISARLAKA FORTRESS NEAR THE VILLAGE OF ANEVO (Ivan Dzhambov – djambov@uni-plovdiv.bg, Petya Kaloferova) A semi-sunken-floored dwelling was explored in trenches F1 and F2, in the center of the fortress. Stones, bricks and sherds of the Early Byzantine period of the fortress were reused for constructing its foundations with a bonding medium of mud. Fragmentary wall plaster was found. Fragments of a dolium reused for a frame of a hearth containing burned animal bones were discovered inside the dwelling. The dwelling was burned. The finds from trenches F1 and F2 include windows glass, an iron hinge and a latch for a door, Early Byzantine (4th – 6th centuries AD) and mediaeval (9th – 10th centuries) pottery, and a coin of 20 nummi minted by Justinian I. Part of the proteichisma situated at 16 m to the north of the northern fortification wall was explored in trench F3. The northern proteichisma has the same features as the eastern proteichisma: the width of the wall and its construction with a bonding medium of mortar, the size of the flying buttresses (90 cm by 80 cm) and the distance between them (2.90 m). Most likely, the northern proteichisma had an entrance. The finds include an iron cramp, fragments of a dolium, Early Byzantine pottery with traces of burning and mortar on its surface.
