Commissioned by Justinian in the 540s, this Byzantine church is almost exactly as old as its near neighbour, Aya Sofya. Used as an arsenal for centuries, it is now open to visitors but the entrance fee is exorbitant considering the fact that there are no exhibits inside.
The serenely beautiful interior and superb acoustics make this one of the most soughtafter venues for the İstanbul International Music Festival. To attend a festival event here try your luck at the temporary box office located outside the church or online at Biletix .
