Originally constructed in 537 AD during the reign of Byzantine Emperor Justinian I, the Hagia Sophia was designed to serve as a cathedral for Constantinople (modern-day Istanbul). Its massive dome and intricate mosaics showcased the grandeur of Byzantine art and engineering.
In 1453, following the Ottoman conquest, Sultan Mehmed II converted the Hagia Sophia into a mosque.
During this period, Islamic elements such as minarets and calligraphy were added, while the Christian mosaics were carefully preserved beneath the plaster. In 1935, the Hagia Sophia became a museum under the leadership of Mustafa Kemal Atatürk, reflecting Turkey’s commitment to cultural inclusivity. In 2020, it was reconverted into a mosque, yet it remains open to visitors from all walks of life.
