Architecture, as a form of culture, represents the historicity of a place. In Asia, more often than not, more than one location, history and culture are simultaneously inscribed upon architectural objects that are located in one place. Formerly colonised and some quasi-colonised cities and countries are especially conspicuous; Taiwan is one remarkable example of the later. This paper argues that Taiwanese architecture, characterised by this Asian complexity along with Taiwan’s particular social and cultural registration, hybridises different forms of cultural-politics, either diachronically or synchronically, as an important reference of Asian ‘colony architecture’. This paper explores this colonial historicity by examining a historic built case in Kaohsiung, Taiwan – the Kaohsiung Museum of History. Modern Taiwan’s postcoloniality in culture and society are theorised through articulated eclecticism and hybridity registered with the case in the discussion to represent the building’s history and inscribed coloniality. It is to ask: how is the building, in different aspects, shaped by its representation of Taiwan’s (post)colonial historicity, and what is its reciprocal role in Taiwan’s history? This paper discusses these questions in terms of (post)colonialism, form and representation.
