Global Church Council Voices 'Grief and Dismay' at Turkey's Hagia Sophia Decision AFP GENEVA, SWITZERLAND - The World Council of Churches, which represents 350 Christian churches, said Saturday it wrote to Turkey's president expressing "grief and dismay" over his decision to turn the Hagia Sophia museum back into a mosque. "Hagia Sophia has been a place of openness, encounter and inspiration for people from all nations and religions" since 1934 when it was turned from a mosque into a museum, the Geneva-based council's interim general secretary Ioan Sauca said in the letter. The 1,500-year-old UNESCO-listed site was initially an Orthodox Christian cathedral that became a mosque following the Ottoman conquest of Istanbul in 1453. .
