Erdogan Plans Controversial Quran Reading at UNESCO Site Anthee Carassava ATHENS, GREECE - For over a thousand years, Istanbul's Hagia Sophia operated as the biggest Greek Orthodox Christian church before being converted into a mosque, then a museum and, most recently, a United Nations-designated cultural landmark. At the direction of Turkish President Recep Tayyip Erdogan, a reading of the Quran will take place Friday at the ancient building. In announcing his decision, Erdogan said the Conquest Sura, a section of the Quran, would be recited at the site, and that prayers would also be held as part of a celebration organized by the country's culture ministry in commemoration of the fall of the Byzantine empire in 1453. .
