PLISKA (Yanko Dimitrov – yanko_aim@mail.bg, Hristina Stoyanova) The northern part of the Long Timber Building was discovered in Sondage No. I in front of the eastern gate of the fortress. The building was situated along the southern and the eastern fortification walls and dated to the end of the 8th – first decades of the 9th centuries. Sherds and four coins were found: a follis of Constantine VII Porphyrogennetos and Zoe minted in AD 914 – 919, two coins of Nikephoros II Phokas and an anonymous Byzantine follis of Class A2 (AD 976 – 1030/1035). The stone pavement was done soon after the demolition of the timber building and dated from the first quarter of the 9th to the beginning of the 10th centuries. The passage in the building was 8.80 – 9 m wide and its axis coincided with the axis of the passage in front of the eastern gate of the stone fortress and the axis of the eastern gate of the Large Timber Fortification. Sectors from the northern surrounding wall of the complex of houses and farm buildings of the second half of the 9th – beginning of the 11th centuries were explored. Three stages in the stone constructions were documented. A pavement parallel to the western surrounding wall was discovered. Sherds of the 10th century were found above the pavement and sherds of the 9th century below it.
