The church is mentioned for the last time on May 28, 1453. On that day, which was the eve both of the Saint's feast and also of the end of the Byzantine Empire, the Emperor Constantine XI with the Patriarch went to pray into the church, which was adorned with garlands of roses. Afterward Constantine left for the last struggle. Many people remained all the night in the church, praying for the salvation of the city. On the morning the Ottoman troops, after entering the city, reached the building, still adorned with flowers, and captured all the people gathered inside, considering them as prisoners of war. The relics were thrown away and the body of the Saint was cast to the dogs.
