The archaeological excavations of 2008 were located in the Episcopal quarter of the ancient city of Bylis. The excavation data suggest that the Episcopal quarter to the southeast of the cathedral (also known as the basilical complex, or Basilica B) of the city, in its final construction phase, during the Later Roman period, was situated in the intersection point of the two perpendicular axis of the city. The first axis is an earlier decumanus, built during the Hellenistic period. It traversed in the eastern and western sides the liturgical annexes of the cathedral, and continued up to the top of the hill, where it joined the cardo, that was protected by a fortification wall of the 6th century AD. The second axes of a north-south direction continued alongside the wall of limestone blocks that divides the upper and the lower parts of the city. The two axes were joined in the yard L, which consisted of several rooms and was detached from the basilica complex. A porticoed entrance in the eastern side of the yard gave access to the Episcopal quarter. The northern side the yard was confined by building N (probably a storehouse) and two rooms of the cathedral, while in the south from the large building K-P. This latter, which was constructed on two levels, had 5 rooms opening into the yard (K1-5: where K1 was probably a stable and K2 had an olive grinder), and 3 others in the southern façade (P1-3: where P3 was perhaps the kitchen of the building). To the west the yard was blocked by the later building D. Another entrance in the north-western side of the yard emerged directly in the cardo, allowing the circulation of storage foods found in the nearby warehouses, the supply with raw goods and the distribution of wine and olive products, as well as the sustenance of the livestock transport. The materials revealed suggest that the Episcopal quarter, served not only for liturgical purposes but it was also a residential quarter related to economical activities.
The excavations in building N showed that room N2 is likely to have been used as warehouse (cellar?) and N5 an area used for grape pressing and wine production. The peaked roof of room N2 seems to have been supported by a doubled arched hold on a central column. The excavations of this area revealed a masonry bench, abutting the eastern wall, and a number of pithoi, which were set in a regular line and were covered on the inside with bitumen. In room N5, the excavations uncovered 3 tanks of rectangular shape, equipped with staircases for removing the grape remains, and 4 pithoi placed against the eastern wall, which were possibly used as wine containers. In the lowest stratigraphic levels of room K4, a floor level was uncovered, along with a doorway in the southern wall. The doorway, followed by a threshold, was partly blocked by the staircase identified in the other room, next to P1A.
