EXPLORATIONS IN AUGUSTA TRAIANA – VEREYA, SQUARE 63A (Dimiter Yankov – dimiter_yankov@yahoo.com) A cardo was explored. It is a continuation of the street to the west of the insula, which accommodates the House with the Mosaics, nowadays located at General Stoletov Street. The excavated part of the cardo is 10.30 m long and 5.95 m wide. During the first phase of use, the street was paved with stone slabs that measure from 50 cm by 70 cm to 1.75 m by 1.50 m. A water-conduit of terracotta pipes, 16 cm in diameter, was discovered in the eastern part of the street, dug at 55 – 60 cm under the level of the pavement. The street was constructed at the end of the 2nd century AD and most likely, the water-conduit was built until the mid 3rd century AD. During the first occupation period (2nd – 3rd centuries AD), a building, possibly with a peristyle, existed to the west of the street. Its walls are up to 72 cm thick. During the second occupation period (4th century AD), walls, up to 75 cm thick, were built from the both sides of the street. At 7.25 m to the west of the western wall, a second identical wall was explored. Probably, these were fence walls. During the third occupation period (6th century AD), a building existed in the southwestern corner of the site. Its walls are 75 cm thick. The northeastern corner of the building was explored. A floor level of a house constructed of sun-dried bricks, which dates to the end of the 5th – 6th centuries AD and was destroyed by a fire, was documented to the east of the street. A mediaeval stratum of the 10th – 12th centuries was documented and a hearth, a domestic oven and a wall were discovered. A house and three pits of the 17th – end of the 19th centuries were explored. The finds include Late Antique and mediaeval sherds and coins, a marble head of Dionysus, etc.
