Hagia Sophia, this is not the one in Harbin. This was the church that was converted into a mosque after the Byzantine Empire was occupied by Turkey. It is said to be the top ten cathedrals of the earth, but I also photographed the churches of the seven and eight eight and eight. It felt that the protection of the Hagia Sophia was too bad, the murals on the walls began to fall off, and the whole building was difficult for me to agree that it was the top ten church in the earth. I can finally get out of the way and leave Turkey without regret.
