The Bishop’s Basilica is the largest of four ancient basilicas found in Parthicopolis, today’s Sandanski in Southwestern Bulgaria. It consists of an entire complex of early Christian buildings, and was the seat of a bishopric in the late Antiquity.
It was first discovered in 1989 by Vladimir Petkov, then and current director of the Sandanski Museum of Archaeology, and has been excavated ever since. Towering at 16 m and with a length of 30 m and width of 22 m, the basilica is unique for its Early Christian mosaics and murals, including depictions of fish and birds.
The Bishop’s Basilica must not be confused with Bishop John’s Basilica, which is also one of the four ancient basilicas in Parthicopolis in today’s Sandanski in Southwestern Bulgaria. It is especially known for a mosaic inscription found in the center of its narthex stating that it was built by a “Bishop John”; hence, it has also become famous as Bishop John’s Basilica.
In 2013, the Sandanski Municipality started the partial restoration of the two basilicas, the Bishop’s Basilica and Bishop John’s Basilica, and the Early Christian complex in Parthicopolis with an EU grant of BGN 6.1 million (app. EUR 3.1 million) under Operational Program “Regional Development”. The basilicas and the adjacent buildings were destroyed by arson during barbarian invasions, possibly by the Slavs who tried to capture Thessaloniki in the second half of the 6th century.
