"I hope for the prudence of Turkey's state leadership. Preservation of the current neutral status of Hagia Sophia, one of the greatest masterpieces of Christian culture and a church–symbol for millions of Christians all over the world, will facilitate further development of the relations between the peoples of Russia and Turkey and help strengthen interfaith peace and accord", Kirill said in a statement, as quoted by his press office.
The head of the Russian church added that changing Hagia Sophia's status will "inflict great pain" on the Orthodox-majority population of Russia.
Last year, Turkish President Recep Tayyip Erdogan suggested that Hagia Sophia, formerly the Church of the Holy Wisdom, which used to be an Orthodox Christian cathedral before becoming a mosque and then a museum, could become a mosque again with free admission. Earlier in July, Turkey's Council of State held a meeting on the matter, and a final decision on the fate of the UNESCO World Heritage Site is expected to be made by mid-July.
Greece and the United States have also called on Turkey to preserve the museum states of Hagia Sophia. Ankara considers the issue to be Turkey's internal affair and opposes any foreign intervention in the decision-making process.
