The Hagia Sophia Church in Nesebar, also called the Old Bishopric, stands in the old town of Nesebar in eastern Bulgaria, a UNESCO World Heritage Site. It was built in the late fifth or early sixth century, and its present appearance dates from a reconstruction at the beginning of the ninth century. It served as the cathedral of the Nesebar bishopric in the Middle Ages.
It is a three-naved basilica, about 25.5 meters long and 13 meters wide, with a semicircular apse, a narthex and an atrium. Two rows of five pillars divide the naves. The masonry is mixed stone and brick, and it is the largest surviving above-ground church in Nesebar.
Venetians looted it in 1257, and many relics went to the Church of San Salvatore in Venice. It was abandoned in the eighteenth century.
