ARCHAEOLOGICAL EXCAVATIONS IN PLISKA (Yanko Dimitrov – yanko_aim@mail.bg, Hristina Stoyanova) The explorations of the long stone building of the 10th century, the foundation of the surrounding wall built of bricks bonded with clay and the preceding pits from timber columns and trenches from timber buildings dated to the Capital Period of Pliska continued. About 100 pits from timber columns and sectors from two trenches of the southern part of the long timber building (the earliest structure in the explored area) were documented in squares 1–5/G–D. Three pits (Nos. 1 – 3) were explored in squares 3–4/G and 5D: initially they were storage pits and later became midden. The pits contained material from the end of the 10th – first half of the 11th century. A layer, 40 cm thick, containing ash, charcoal, fragments from terracotta melting pots and pottery from the end of the 8th – first half of the 9th centuries AD, was explored in squares 1/G–D. Two trenches and pits for timber columns of a timber building, not yet identified, were documented below the layer. Both trenches were situated under the foundations of the southern part of the long stone building. The level of the excavations carried out during the 1970s, situated below the plinth of the southern fortification wall of Pliska, was reached in squares 0–1/V, G, D, E. A new sector of the southern foundation of the long stone building, situated parallel to the fortification wall, was discovered.
