Sabancı University's Sakıp Sabancı Museum is located in Emirgan, at one of Istanbul's oldest settlements on the Bosphorus.
In 1925, Prince Mehmed Ali Hasan of the Hidiv family of Egypt commissioned the Italian architect Edoardo De Nari to build the villa, now the museum's main building, and it was used as a summer house for many years by various members of the Hidiv family.
After the mansion was purchased in 1951 by industrialist Hacı Ömer Sabancı from the Hidiv family as a summer residence, it came to be known as Atlı Köşk, “The Mansion with the Horse”, because of the statue of a horse (purchased in the same year) that was installed in the garden; the statue is the 1864 work of the French sculptor Louis Doumas.
A second horse sculpture on the grounds of Atlı Köşk that gave the mansion its name is the cast of one of the four horses taken from Sultanahmet square in Istanbul when it was looted by Crusaders during the Fourth Crusade in 1204 and removed to the Basilica of San Marco in Venice.
After the death of Hacı Ömer Sabancı in 1966, Atlı Köşk began to be used permanently as a home by Sakıp Sabancı in 1974 as the eldest of the family, and for many years housed Sakıp Sabancı's rich collection of calligraphy and paintings. In 1998, together with its collection and furnishings, the mansion was bequeathed to Sabancı University by the Sabancı family to be transformed into a museum.
With the annex of a modern gallery, the exhibition areas of the museum opened to visitors in 2002; with a further extension of the layout in 2005, the technical level of the museum reached international standards.
Today Sabancı University Sakıp Sabancı Museum presents a versatile museological environment with its rich permanent collection, the comprehensive temporary exhibitions that it hosts, its conservation units, model educational programs and the various concerts, conferences and seminars held there.
