Have you ever imagined to see Orthodox frescos of Mother Mary and Jesus in a mosque? Fertek (Fertakaina) Mosque was a Karamanlis Church of Archangelos Michael & Gabriel built by Kara Maho oğlu Hajji Nikola in 1835 in Fertek, Cappadocia, Turkey. The church has been a mosque since the population exchange between Greece and Turkey in 1923. However its architecture and frescos were left intact simply covering with curtains.
In Byzantine and Orthodox images, inside each of the bars of the cross in Christ's halo is one of the Greek letters ώ Ό Ν making up I AM—literally, "the Existing One" — indicating the divinity of Jesus.
