This paper looks at how place-making at a historic site via collective memory provokes and embraces issues of memory and representativeness. It examines how the power of place-making knowledge and the power of collective memory compete and negotiate in the city of Gwangju, South Korea. Through the analysis, primarily, of archives and in-depth interviews, the research investigates the case of conflicts surrounding the construction of the Asian Culture Complex in Gwangju. The construction included the demolition of the Byeolgwan, where ordinary protesters were killed in the 18 May democratic uprising of 1980. During public consultations and the consensus-making process, victims developed an adaptive preference and agreed to changes proposed without realising what exactly would happen. The controversy that emerged after they expressed their belated criticism clarified the collective memory of 18 May. Intellectuals challenged the power of the 5.18 organisations, bearing professional knowledge and appropriate manners in debates. The conflict contributed to the re-arrangement of power relations in the city and to the clarification of issues that had not been openly discussed before. The power of mourning and symbolising tragedy, usually located with the victims of such tragedy, is challenged by the power of place-making for the future.
