ARCHAEOLOGICAL EXPLORATIONS IN PLISKA (Stanislav Ivanov –stanislavivanovarh@gmail.com) Two rooms in Building No. 2, consisting of parallel rooms arranged in a line, were explored. A ceramic pilgrim flask and sherds from dolia and a jug were found. Judging from the coins and the finds, the building was not built before the end of the 10th century and probably dates only in the 11th century. Pits from timber columns were discovered under the floor of Building No. 2. The pits were arranged in a line oriented east – west, following the line of the pits explored in 2008. The pits had a quadrilateral layout and had pads of three courses of fragmentary bricks on their bottoms. Four storage pits (Nos. 5 – 8) were discovered under the floor of Building No. 2. The finds in the pits dated after the middle of the 10th century. Four Christian graves (Nos. 9 – 12) from the necropolis of the Palatial Church were explored. Three of the burials belonged to children. The deceased in graves Nos. 9 and 12 were rested in burial chambers constructed of bricks and stones. A drain passing through an opening in the plinth of the brick fortification wall of the Citadel was discovered. Another opening close to the southwestern corner of the brick fortification wall was documented with a drain collector box in front of it. Two drains coming from the Citadel entered the collector box and a third drain oriented to the southeast ran out from it. The monumental building of the first half of the 9th century AD was thoroughly explored. It measured 15.70 m by 9.50 m. The foundations of the building were 0.90 – 1 m wide and its walls were constructed of ashlars bonded with mortar.
