The Rockefeller Museum, named for American philanthropist John D. Rockefeller Jr., is one of the Jerusalem's most exquisite gems. Off the beaten path, the nearly 70 year-old Museum is housed in an ornately designed building from the period of the British Mandate. Architect Austen St. Barbe Harrison designed the building, located adjacent to the northeastern corner of the Old City, to seamlessly integrate architectural elements from east and west. Situated in a magnificent white limestone edifice in eastern Jerusalem, the Rockefeller Museum houses an extraordinary collection of antiquities unearthed in excavations conducted in the country mainly during the time of the British Mandate (1919-1948). The Rockefeller Museum is operated by the Israel Museum, Jerusalem.
