PLISKA (Konstantin Konstantinov – konstantinov_k_t@yahoo.com, Gergana Ilieva, Ivailo Kanev) The exploration of the surrounding wall of the architectural complex continued to the north of the parallel rooms arranged in a line, which were excavated in 2014 – 2015 and were situated in the southeastern sector of the outer yard. Sondages were carried out in Rooms H1 and H2 and to the west of Room H3. An earlier dugout was documented. The excavations of the trenches launched in 2011 continued in the northeastern part of the inner yard of the architectural complex. The pavement continued to the south and was built of stone slabs. The building documented in 2011 was entirely excavated. It measured 7.60 m by 3.80 m and there were ashlars with postholes situated in its corners and in the middle of the southern and the northern walls. The floor was plastered with mortar. The building was a chapel with a narthex, 1 m by 3.80 m in size, a nave, 4.40 m by 3.80 m in size and a semicircular apse. A later oven was discovered in the nave. The excavations of the building consisting of parallel rooms arranged in a line were launched. It was later than the other buildings in the architectural complex. Two of the rooms were excavated, 3.80 m by 4 m in size. The foundations of the walls were 80 cm wide. Earlier foundation trenches with postholes were documented in the northeastern part of the inner yard. Pit No. 6 was discovered; it destroyed part of the stone pavement and contained sherds, fragmentary building ceramics, pieces of mortar, charcoal, a fragment from an ashlar with graffiti, a fragment from tegula with an image of a bird, three bronze finger-rings and a bronze belt buckle. Pottery Kiln No. 3 was explored to the southeast of Pit No. 6. The structures discovered during the excavations dated from the mid 9th to the end of the 11th centuries AD.
