PRESLAV (Stoicho Bonev – stoi40_50@abv.bg, Radostina Georgieva) The explorations of the building discovered in 2010 in the southwestern part of the Royal Palatial Complex continued. Its walls were 1.50 m wide, constructed of ashlars, 0.80 – 1 m long, 40 – 60 cm wide and 40 cm high, bonded with mortar. The foundations of the building were also constructed of ashlars and were 1.70 m deep. The building was 20 m wide and consisted of three parallel wings oriented east – west along their longitudinal axes. There was a hall in the central wing. The hall was 5 m wide and was paved with marble slabs, up to 1.20 m long, arranged over a mortar layer. The northern and the southern wings consisted of parallel rooms arranged in a line. The third room in the northern wing was paved with limestone slabs and the third room in the southern wing was paved with marble slabs. Details from the architectural decoration of the building were found: cornices with torus, small columns from windows, marble frames and small plates from floor panels, small plates of green shale from multicolor floor panels. The building dated to the end of the 9th – first half of the 10th centuries and it may be identified as the Residential Palace of the king, which belonged to the complex of the two central palaces with throne halls.
