PLISKA (Yanko Dimitrov – yanko_aim@mail.bg) The explorations in the Eastern Sector of the Citadel continued. In Trench III, sectors from trenches and postholes from timber structures of the end of the 8th – 9th centuries AD were discovered. A stratum up to 70 cm thick was explored, containing sherds of the 10th – beginning of the 11th centuries. In Trench II, the explorations of the Large Timber Building of the first half of the 9th century AD continued. Seven postholes that accommodated timber columns c. 40 cm in diameter, were discovered. The building was separated in equal perpendicular rooms that were 8 m by 4 m in size. Sherds of the first half of the 9th century AD were found. The building was reconstructed and three of its perpendicular rooms were unified in a new one, c. 12 m by 6 m in size. A complex of three pits was explored, each one c. 3.20 m by 1.60 m in size and c. 70 cm deep. The pits were arranged in a line oriented east – west. Remains from ovens were discovered in the pits. The complex dated to the end of the 8th – first half of the 9th century AD and probably was used for cooking for the feasts organized by the proto-Bulgarian khans.
