EXPLORATIONS IN AUGUSTA TRAIANA – VEREYA, SQUARE 66A (Dimiter Yankov – dimiter_yankov@yahoo.com) Two streets (cardo and decumanus) were explored in the northwestern part of Augusta Traiana. Probably, the newly discovered cardo lead to the western side of the thermae, while to the east it reached the Early Christian church found in 2004. The excavated segment of the street is 27.50 m long, 6.10 m wide and is paved with stone slabs. A drain, 50 cm wide and 75 cm deep, was discovered in the western part of the street. A water-conduit of terracotta pipes, 18 cm in diameter, was explored in the eastern end of the street, 85 cm below the level of the pavement. There are remains of a building and a stylobate at the western end of the street. Two bases of columns and a low altar were discovered. The newly discovered decumanus is 6.50 m wide. A drain, 55 cm wide and 50 cm deep, was discovered in the northern part of the street. There is drainage, 35 cm wide, in the southern part of the street. The constructions were built in the end of the 2nd – beginning of the 3rd centuries AD. The building located at the western end of the cardo had at least two phases of reconstruction, but no later than the second half of the 4th century AD. The mosaics’ pebbles and the mortar plaster, which were discovered, allow us to suppose that the portico of the building had a mosaic floor during the first occupation period. Remains of a wall, a few pits and a hearth, located in the southern part of the portico and belonging to the Middle Ages, were explored. The finds include an Early Christian bronze lamp, a marble portrait head, a capital of a column probably belonging to the portico, fragments of amphorae, etc.
