DEULTUM (Krasimira Kostova – kr.kostova@mail.bg) Sondage No. 6 was carried out in Sector East – South, to the south of the latrine, in order to precisely detail the stratigraphy of the thermae. A pit of AD 400 – 450 was excavated, dated by coins of Theodosius II. The southern wall of the thermae was discovered, closing the latrine. An area was explored in the western part of the thermae, situated to the north of the Nymphaeum and covering part of the western cardo and the stylobate that was excavated in 1987 – 1988. A sunken-floored house of the 9th century AD was excavated, containing sherds, including from proto-Bulgarian pots and Byzantine amphorae of Saraçhane Type 30. Sunken-floored houses of the 8th – beginning of the 9th centuries AD were documented as well. A drain and a wall were excavated, dug into a layer with traces from fire of the end of the 6th century AD, dated by coins of Justin II. Parts of the floor of a building were explored. It was constructed of sun-dried bricks with a roof covered with tiles and was burned down at the end of the 6th century AD. The bottoms of two dolia, nine terracotta lamps, an amphora LR 1, a bowl and a lid of a pot were discovered on the floor. A house of sun-dried bricks with a roof covered with tiles was built over the stone plinth of the Late Antique stylobate. The western cardo was paved with stone slabs and it was functional until the beginning of the 6th century AD.
