The Constitutional Court of Turkey decided that Hagia Sophia will not be turned into a place of Muslim worship after an appeal made by a private organization called “Authority for Historical Monuments and Environment”.
The Temple that was built in the 6th Century AD by the Byzantine Emperor Justinian as a Christian Cathedral, is now a Museum and will remain a Museum.
The organization had requested the Turkish government in 2004 to make arrangements to open Hagia Sophia as a mosque but did not receive a response.
Then, in 2015, they appealed to the Council of State, which rejected their request.
The organization claimed that the denial of the conversion is against freedom of religion.
