 Abandoning Rationalism, Turkish architects tried to design their buildings in more flexible and fragmented forms.Important works from this period are the Vakıflar Hotel in Istanbul (1968, today the "Ceylan Intercontinental Hotel"), Middle East Technical University Campuses (1961) in Ankara, Istanbul Manufacturers' Market (1959), Turkish Historical Society Building (1967), Grand Ankara Hotel (1960, today the Rixos Grand Ankara Hotel) and Atatürk Cultural Center (1969) in Istanbul.As a result of economic and social turbulence, architecture in Turkey suffered also in the 1970s.
