[2] As evidenced by remnants of a column to the south of the church and a cistern to its northwest, it originally formed part of a larger complex.
The interior decoration consists of rich mosaics on the upper levels, inspired by Constantinopolitan models.
These too show influence from Constantinople, and were possibly executed by a workshop from the imperial capital, perhaps the same which decorated the Chora Church.
As was their usual practice, the Ottomans covered the mosaics and frescoes with plaster, after they removed the gold tesserae.
