Sakıp Sabancı Museum holds two museums at one address. In the wood-panelled rooms of an old waterfront mansion sits one of the world's richest collections of Ottoman calligraphy — imperial edicts, sultans' monograms, illuminated Korans — beside Turkish painting from Osman Hamdi Bey onward. Next door, a glass gallery built for big travelling shows has hosted Picasso, Rodin, Dalí and Rembrandt, drawing queues that wrapped down the hill. Outside, a sloping garden runs to the Bosphorus and a terrace café watches the tankers slide past.
This was somebody's house long before it was a museum, and it still behaves like one. Inside, you move from panelled rooms a family actually lived in into a modern exhibition wing, and the two halves never quite settle together. The calligraphy rooms stay quiet and unchanging, a collection built over a lifetime. The wing next door turns over show after show and brings the queues.
