PRESLAV (Rossina Kostova – korina68bg@yahoo.com, Kazimir Popkonstantinov) The explorations of the Northern Building continued. Its walls were 80 cm wide. A room 10 m by 4.40 m in size was explored and the finds included tegulae and imbrices, sherds of the end of the 10th – 11th centuries, an anonymous Byzantine follis of the Class A1 (AD 970 – 976) and a lead seal of monk Georgi the Bulgarian Synkellos (first half of the 10th century AD). This is the fifth seal of Georgi the Bulgarian Synkellos discovered in the monastery and so far, eight of these seals are known. The southern and the western walls of the Rectangular Building were dug into layers with debris and traces from fire. Fragmentary bricks and roof-tiles were discovered in the buildings and a layer with traces from fire was discovered beneath, containing sherds of the 10th – 11th centuries, a mouth of a dish with polychrome decoration produced from white earthenware, a bronze belt appliqué and lead styli. A circular structure 2 m in diameter was discovered, built of stone slabs and boulders bonded with clay, with a storage pit located beneath. The finds from the excavations included 11 coins: two anonymous Byzantine folles of the Class A1 (AD 970 – 976), an anonymous Byzantine follis of the Class B (AD 1030 – 1050), seven coins of the first half of the 13th century and a Roman coin. The Northern Building and the Rectangular Building dated to the 10th – 11th centuries and were built near to Church No. 5 on a site that was previously occupied, while the earlier structures were burned and destroyed.
