The world-famous Hagia Sophia museum in Istanbul - originally founded as a cathedral - has been turned back into a mosque.
Turkey's President Recep Tayyip Erdogan announced the decision after a court annulled the site's museum status, BBC reported.Built 1,500 years ago as an Orthodox Christian cathedral, Hagia Sophia was converted into a mosque after the Ottoman conquest in 1453.
In 1934 it became a museum and is now a Unesco World Heritage site.
Islamists in Turkey long called for it to be converted to a mosque but secular opposition members opposed the move. The proposal prompted criticism from religious and political leaders worldwide.
