THE MONASTERY OF CHARGUBILYA MOSTICH (Kazimir Popkonstantinov, Rossina Kostova – korina68bg@yahoo.com) The foundation of the building consisting of parallel rooms arranged in a line and located to the south of the “Church of Mostich” was constructed of boulders bonded with clay. The building was demolished after the construction of the church. Part of a building, discovered at 12 m in length for the moment, was explored to the southeast of the church. The sherds date to 10th century AD. Foundations of two buildings were registered to the south of the church. Sherds of the end of 10th – 11th centuries AD prevail. Tomb No. 5 was discovered in front of the western entrance of the “Church of Mostich”. It has a burial chamber built of bricks, covered with a stone slab and plastered with mortar. A brick with incised Greek cross under an arch was placed on the eastern side of the tomb. The burial chamber is divided in two sections. Re-buried remains of a woman were discovered in the eastern section, which is smaller in size. A brick with a Cyrillic inscription in Old-Bulgarian was discovered to the northern wall of the eastern section: СЕ ЕСТЬ СVНКЕЛ МАТЕРH СРДОБОЛ ПОГРЕБЛЪ. The text is a replica of an inscription on a marble funerary monument placed above the floor, which was discovered in 1952. The Synkellos who has re-buried his mother, according to the inscription, was most probably Georgi. Three seals of Georgi the Bulgarian Synkellos (first half of the 10th century AD) were found 20 years ago near the “Church of Mostich”. The western section of the tomb contained re-buried bones of a man c. 25 years old, a woman 30 – 35 years old and five children from 5 months to 2 years and 7 months old. Two Christian graves were discovered in the southern half of the portico. A man, c. 35 years old and 181 cm in height, was buried in grave No. 25. Two Christian graves were explored to the north of the portico. A pavement of slabs was discovered around church No. 5. The pentahedral apse of the church is built on a step lying on a platform constructed of boulders and mortar.
