The majestic building was founded around 1,500 years ago as a cathedral and is widely regarded as the foremost example of Byzantine Christian architecture in the world. Following the rise of the Ottoman Empire, it became a mosque, but in 1934, was designated a secular museum, shared by Christians, Muslims and those of all faiths or none, alike.

President Recep Tayyip Erdogan signed the decree following years of campaigning by a cultural association, and the decision earlier in the day by a Turkish court, handing control of the building over to the nation’s religious directorate, according to news reports, allowing it to reopen for worship as a mosque.
Reacting to the decision, Director-General of UNESCO, Audrey Azoulay, described the building as "an architectural masterpiece, and a unique testimony to interactions between Europe and Asia over the centuries. Its status as a museum reflects the universal nature of its heritage and makes it a powerful symbol for dialogue."
Call for dialogue
UNESCO said in a statement issued before the decree, that it had written to the Government and called for “dialogue” with the authorities, “before taking any decision that might impact the universal value of the site.”
Hagia Sophia, is part of the “Historic Areas of Istanbul”, and officially inscribed on the World Heritage List as a museum.
“This inscription entails a number of legal commitments and obligations. Thus, a State must ensure that no modification is made to the outstanding universal value of the property inscribed on its territory”, said the UN’s Educational, Scientific, and Cultural Organization.
No modification ‘without prior notification’
“Any modification requires prior notification by the State concerned to UNESCO and then, if necessary, examination by the World Heritage Committee.”
“Outstanding universal value” is the basis for the decision to inscribe any property on the World Heritage List, the statement continued.
“The texts adopted by the Committee specify that the ‘Historic Areas of Istanbul’ is inscribed notably for ‘its unique integration of architectural masterpieces reflecting the meeting of Europe and Asia over several centuries’ and because ‘Hagia Sophia became a model for an entire family of churches and later mosques, and the mosaics of the palaces and churches of Constantinople, influenced both Eastern and Western art’”.
The agency noted that in line with its designation, the Hagia Sophia “has a strong symbolic, historical and universal value.”
UNESCO called upon the Turkish authorities "to initiate dialogue without delay, in order to prevent any detrimental effect on the universal value of this exceptional heritage, the state of conservation of which will be examined by the World Heritage Committee at its next session."
“It is important to avoid any implementing measure, without prior discussion with UNESCO, that would affect physical access to the site, the structure of the buildings, the site’s moveable property, or the site’s management,” stressed Ernesto Ottone, UNESCO’s Assistant Director-General for Culture. Such measures could constitute breaches of the rules derived from the 1972 World Heritage Convention, the agency warned.
