Sakıp Sabancı Museum grew out of a private family home, and its garden still guards the bronze horse that gave the house its old name, the Atlı Köşk. Built in 1927 for a prince of Egypt's royal Hidiv family and bought by the industrialist Hacı Ömer Sabancı in 1951, the waterfront villa in Emirgan passed to his son Sakıp, who lived here for decades and opened it to the public in 2002 under Sabancı University. Inside, one of the world's richest collections of Ottoman calligraphy — imperial edicts, sultans' monograms, illuminated Korans — sits beside Turkish painting from Osman Hamdi Bey onward.
You move from the wood-panelled rooms of the old mansion into a glass gallery built for the big travelling shows — Picasso, Rodin, Dalí and Rembrandt have all taken an Istanbul turn here, drawing queues that wrapped down the hill. Outside, a sloping garden opens onto the Bosphorus, and a terrace café watches the strait's tankers slide past below. Today the calligraphy rooms stay quiet and unchanging while the exhibition wing turns over show after show, so two very different museums share one address.
