The basilica is built with an unconventional 'opus mixtum' masonry technique using alternating layers of stone and brick.
The original roof was likely constructed of wood and was lost entirely when the building was abandoned after the 13th century.
The central nave was once divided from the side aisles by massive masonry pillars rather than columns.
The church was part of the Metropolitan complex that governed the religious life of the medieval Nessebar peninsula.
The floor was originally covered with intricate 5th-century polychrome mosaics, sections of which were recorded by archaeologists before being protected.
It is the largest of the many churches found on the Nessebar peninsula.
The Church of Saint Sophia, locally known as the Old Bishopric, is a 5th-century Byzantine basilica located in the heart of Nessebar's Old Town. The structure stands as a three-nave basilica measuring 20 meters in width and 25 meters in length, featuring an expansive apse and two side aisles. It was primarily constructed using a combination of stone blocks and three rows of red bricks, a signature of the era's regional masonry. The current skeletal remains represent the primary structural phases dating from the late 5th to early 6th centuries, with significant modifications occurring during the 9th century. Archaeological evidence suggests the building served as the seat of the Bishop of Nessebar for several centuries. The church was partially destroyed by Venetian forces during a 13th-century raid and subsequently abandoned. Today, the site functions as an open-air historical monument within a UNESCO World Heritage-listed peninsula.
