It was shocking. I didn't expect such a big hand in foreign countries, which made me stunned.
The Hagia Sophia in Trabzon is used as the central church of the former royal family Komunin who exiled from Constantinople. After the Ottoman Empire conquered this place in 1461, it was converted into a mosque. It is a combination of Christianity and Islam. The murals are not exquisite and simple, but they are precious because of their age. This church was later used as a fortress. The building looks very similar to the castle from the outside. The cannon used as a fortress in the courtyard has long been rusty.
