Since the 1970s, the search for Taiwan ’s cultural identity has entered another stage. Diplomatic dilemmas put an end to the claim that the KMT government was the only legitimate representative of China. The government and its people are forced to confront the challenging issues of Taiwan’s identity. During this period, critical attitudes towards modernism began to emerge in the U.S. with the rise of new theories of regionalism and postmodernism. These have provided academics in Taiwan with new tools and methodologies for its pursuit of cultural subjectivity and its criticism of modernity. Architects initiated investigations of traditional architecture in Taiwan searching for its architectural subjectivity and autonomy. However, architectural practice in Taiwan in the 1970s was still dominated by architectural modernism. In the 1980s, vernacularism and postmodern historicism were first introduced to Taiwan. These were widely appropriated in speculative real estate projects. Vernacularism also inspired Yilan county government together with architects Ying-Chun Hsieh and Team Zoo in constructing several Yilan Houses and The Dongshan River Water Park. After the 2000’s, the DPP (Democratic Progressive Party) administration also adopted a similar method to forge a Taiwanese identity through architectural competitions and projects. The competition for The Capital Plaza successfully triggered public discussion on the history, the future, and the identity of Taiwan. The New Campus Movement after the 921 Earthquake introduced participatory design methods and educational reform concepts into school reconstruction. In addition, by organizing international architectural competitions, a new image of Taiwan has been established internationally through the reshaping of architectural landscapes and gateways of Taiwan. Finally In the planning of the Southern branch of The National Palace Museum, the Museum’s cultural role was reimagined. And with the construction of the museum, a new subjectivity and autonomy of Taiwan’s cultural identity has been established.
