The visible remains in the town centre belong to the Roman and Byzantine peri-ods. Almost all of the building material is Roman but the buildings’ last phases indicateByzantine use and the Byzantine building with three rooms built from Roman spolia isnoteworthy. There are three more rooms placed in the east-west direction, just below thisByzantine building. To the east of these buildings there is a row of rooms extending paral-lel to the slope. This area was suitable for the Roman settlement’s square, i.e. the agora,understood to have been heavily rebuilt from Roman spolia during the Byzantine period.
During surveys 18 inscribed blocks were found. In the centre are four sarcophagus podiums withlion paws, one ostothek piece, a small altar with a lightning motif in relief and half of asundial. Furthermore, some profiled blocks with slight curvature indicate the former pres-ence of an exedra. Other architectural blocks reveal information regarding the buildingsof the Roman period town. It is thought that some of the honorary inscriptions were origi-nally placed on a monumental gateway. Because all of the buildings underwent significantmodifications during the Byzantine period with their material re-used elsewhere, it is very difficult to determine the plans and precise functions of these buildings. The most impor-tant building dating from the Byzantine period is a well-preserved small church.
A rock-cut inscription was discovered at Gavurbeleni. This rock-cut inscription comprises the initials of the names of two citiesand marks the border between Onobara and Trebenna, or between Typallia and Onobara.The inscription reads OTO and here O is certainly to be identified with Onobara but we are not sure whether T stands for Trebenna or Typallia.
