Because of neighboor buildings, it was difficult to frame correct. I’ve used Pentax K10D.
Kalenderhane Mosque (Turkish: Kalenderhane Camii) is a former Eastern Orthodox church in Istanbul, converted into a mosque by the Ottomans. With high probability the church was originally dedicated to the Theotokos Kyriotissa. This building represents one among the few still extant examples of a Byzantine church with domed Greek cross plan.
It is located in Vefa, Fatih.
