EXPLORATIONS IN DEULTUM (Hristo Preshlenov – hristo.preshlenov@abv.bg) The explorations of the decumanus and the adjacent buildings continued. Sector of the street, 13.50 m long, was discovered. It was paved with irregular slabs, from 45 cm by 55 cm to 1 m by 2 m in size and 10 – 30 cm thick, which were arranged over a leveled embankment that contained Early Roman sherds. The sidewalk consisted of two rows of ashlars. The ashlars in the outer row were 25 cm wide, 1.10 – 3.45 m long and 25 cm high, while the ashlars in the inner row were 65 cm wide. To the west of the pair of parallel rooms arranged in a line another one with similar functions was discovered. The street in front of the western parallel room was reconstructed not earlier than AD 330. A drain, 35 cm by 30 cm in size, was discovered to the north of the sidewalk. The secondary construction of two buildings over the decumanus had transformed it into a passage, 1.55 – 1.75 m wide. The western building was constructed in opus mixtum. A pavement of bricks and a collapsed roof of tiles were documented. Fragmentary roof tiles, bricks, sun-dried bricks, burned wattle-and-daub and a follis of Justinian I were found between both buildings. Bronze coins of Licinius I minted in AD 313 – 317, Constantius II or Constans minted in AD 347/348, Constantius II minted in AD 355 – 361 and Valens were found over the decumanus or in the joints between the slabs. A layer with burned debris was discovered. The deformation of the decumanus and the fire probably were related to the seismic activity registered along the Western Black Sea coast in the middle of the 4th century AD. During the second half of the 6th century AD the passage was abandoned. A drain was discovered. It was built inside an occupation layer containing charcoal, burned sun-dried bricks, a follis of Justinian I minted in AD 538/539 and a fragment of amphora of the second half of the 6th – beginning of the 7th century AD.
