Four columns supported the dome.The altar and floor were of marble. The disposition of the tiles on the outer wall show Cufic decorative patterns of eastern origin. Four building phases are recognized from the repairs and reconstructions over the years. Among the medieval monuments known to have existed in the Agora, it is the only one preserved. It was restored to its original form in 1954-1957.The few surviving wall paintings in the central aisle are of the 17th century CE. Wall paintings from other nearby churches have been placed elsewhere in the church.
