EXPLORATIONS IN AUGUSTA TRAIANA – VEREYA, SQUARE 25 (Dimiter Yankov – dimiter_yankov@yahoo.com) The site is located close to the crossing of the cardo maximus and the decumanus maximus in Augusta Traiana. An area of c. 625 sq. m was explored. Two buildings of the 2nd – 6th centuries AD were discovered. Three rooms belong to the first construction period (2nd – end of the 3rd centuries AD) of Building A. A reconstruction was made during the end of the 3rd – beginning of the 4th centuries AD: a new room was built on the place of the previous two eastern rooms. The floor of the two big rooms was leveled and a preparation for mosaics was made. Fragments of mosaics preserved on an area of c. 1.80 sq. m were discovered in the western room. Alternating four-leaved rosettes made in opus tesselatum with stone, glass and ceramic cubes were uncovered. Building A was demolished after the mid 6th century AD. Three rooms of Building B, which had a peristyle, were explored. The preserved part of the building measures 12.50 m by 11.20 m. Its construction should be dated to the second half of the 2nd – 3rd centuries AD, after some parallels with other buildings in Augusta Traiana. The reconstructed room should be dated to the first half of the 4th century AD. Three stone pavements, most likely parts of a square and a street leading to the temple of the Three Nymphs, were discovered. A wall of dry-stone masonry was excavated and sherds of the 9th – 10th centuries and fragmentary glass bracelets of the 11th – 14th centuries were found. Remains of a house of the 18th – 19th centuries were discovered. More than 20 well preserved ceramic vessels, fragments of tobacco-pipes and parts of copper vessels were found.
