The historic Orthodox church was built at the turn of the 4th and 5th centuries, which makes it the oldest church in the city. Until now, only the ruins of its walls and foundations have survived, and weddings and concerts are still held here. The place was entered on the UNESCO World Heritage List.
The church was rebuilt in the 9th century, when it was incorporated into the bishop's complex and served as a cathedral. In its heyday, the building was 25 meters long and 22 meters wide. It had three aisles separated by two rows of stone pillars that supported brick arches. The floor was covered with a mosaic of small colored stones, and the plastered walls were covered with colorful frescoes.
In the thirteenth century, the temple was plundered by the Venetians, taking away many valuable relics. The church performed its function until the 18th century. At the beginning of the 19th century, it fell into ruin, which has survived to modern times.
