Hagia Sophia Mosque
Istanbul's Grand Mosque & UNESCO World Heritage Site
Since July 24, 2020, Hagia Sophia has served as one of the world's most significant mosques, continuing its centuries-old tradition as a place of Islamic worship while preserving its Byzantine heritage.
From Cathedral to Mosque
When Sultan Mehmed II conquered Constantinople in 1453, he immediately converted Hagia Sophia into a mosque. The transformation included adding minarets, a mihrab, minbar, and covering Christian iconography. For 481 years until 1934, it served as Istanbul's principal mosque.
