Sadberk Hanım Museum

Named after the wife of the late Vehbi Koç, founder of Türkiye's foremost commercial empire, the Sadberk Hanım Museum (sadberkhanimmuzesi.org.tr; adult/student/child under 8 ₺450/100/free) is housed in two late-19th-century yalıs in Büyükdere, near Sarıyer. It's a showcase of both Turkish-Islamic artifacts acquired by Mrs Koç and antiquities from the noted Hüseyin Kocabaş collection. The collection includes Chinese, İznik and Kütahya ceramics; Ottoman and Balkan silk textiles and costumes; glass from the early Greek, Hellenistic and Roman periods; and an exquisite collection of jewelry and diadems from the Mycenaean, Archaic and Classical periods. The museum is closed on Wednesdays.
