This thesis consists of collage and installation works. The collage is composed of photographic images of Seoul, before and after the demolition. This work started from the observation that the image of the city brought about by the process of redevelopment and demolition has two aspects: ruin and development. It expresses from the perspective of the observer two different and confusing aspects that the urban redevelopment and ruins bring to the city dwellers. The installation work also reflects the difference between the present and the future of the city through the use of shadows and lighting of discarded industrial waste, and also asks what the city looks like. I was inspired by the works of Robert Rauschenberg, Mark Bradford, and Yang Haegue. I tried to approach the essence of an endless mutual story between society and art from an aesthetic point of view through this thesis.
