Some of my favorite painting in Istanbul-- the fake marble/restoration work that I noticed in the Hagia Sophia, Topkapi Palace, and assorted mosques. It looks great from far away and simple, almost abstract, up close.
This lovely candy cane mosque from afar..
restoration work inside the Hagia Sophia in the early stages looks like this!
