Klishas commented on the decision of Turkey's Hagia Sophia

The right of Turkey to turn Hagia Sophia into a mosque is no doubt, however, Ankara is obliged to ensure its preservation as a cultural heritage of world importance, said RIA Novosti Chairman of the Federation Council Committee on constitutional legislation Andrey Klishas.

The state Council of Turkey on Friday canceled a decision dated 1934, about the transformation of Hagia Sophia into a Museum. Immediately after President Recep Tayyip Erdogan announced that he had signed a decree about the transformation of the Cathedral into a mosque and the beginning of Muslim worship there.

"To decide on the mode of use of St. Sophia, the sovereign right of Turkey. It can not be doubted, the preservation of the monument as cultural heritage of world Orthodoxy must be provided", - said Klishas.

The Hagia Sophia was founded by the Christian Emperor Justinian, and was opened on 27 December 537. Cathedral over a thousand years was the largest Church in the Christian world. After the capture of Constantinople by the Ottomans and the fall of the Byzantine Empire in 1453, the Cathedral was converted into a mosque but since 1934 the building by decree of the founder of the modern Turkish state Kemal Ataturk became a Museum and was included in the world heritage list of UNESCO.
