PLISKA (Yanko Dimitrov – yanko_aim@mail.bg, Hristina Stoyanova) The area between the eastern gate of the stone fortification and the eastern tower of the southern fortification wall was explored. A pair of trenches for the foundations of the Long Timber Building of the end of the 8th – first decades of the 9th century AD was discovered. The building had a passage situated against the passages of the eastern gates of the timber and the subsequent stone fortification walls. The construction of the stone fortification wall occurred while the Long Timber Building still existed, but soon after the stone fortress was constructed the timber building was dismantled. The explorations of the dug out cellar and its timber structure with posts above the ground, dated to the first half of the 9th century AD, continued. Pits that accommodated dolia were discovered and amphora-like pitchers and sherds from jugs were found. During the 10th – beginning of the 11th century, a shelter with roof covered with tiles was constructed over the cellar that was filled with earth. The explorations of the stone boundary wall with foundation built of bricks bonded with clay continued. The wall dated to the end of the 9th – beginning of the 11th centuries and surrounded an area 144/147 m by 85/98 m in size. A trench for the foundation of a timber fence was discovered below it. The eastern one from the pair of trenches for the foundations of the Large Timber Fortification was discovered below the fence and the boundary wall. A trench from the foundation of a timber fence of the last decades of the 10th century was documented in Sondage 9 and it cut sunken-floored houses that previously existed on that place. One of the houses was burned and contained pottery of the second half of the 10th century. The finds from the excavations included bronze belt buckles and appliqués of the 10th – beginning of the 11th century, a bronze cross-encolpion of the 10th century, a fragment from a copper vessel with an inscription in Mediaeval Greek of the 9th – 10th century, 14 coins: 20 nummi of Anastasius I Dicorus minted in Constantinople, anonymous Byzantine folles: one of the Class A1 (AD 969 – 976), eight of the Class A2 (AD 976 – 1030/1035), two of the Class B (AD 1035 – 1040), one of the Class C (AD 1042 – 1050), and one follis of Constantine X Doukas and Eudokia Makrembolitissa of the Class 1 minted in Constantinople.
