Imams will recite verses of the Quran in Istanbul’s Byzantine-era cathedral Hagia Sophia during Friday’s prayers on the anniversary of the city’s 1453 conquest by Ottoman troops, Turkish President Recep Tayyip Erdogan said according to reports Thursday.
Built in the 6th century, Hagia Sophia was the main seat of the Greek Orthodox church. It remained so until it was converted into a mosque after the Ottoman conquest of the city, then-known as Constantinople, in 1453. Source Ekathimerini
