This paper considered city as a palimpsest, and at the same time as a Mnemosyne and archive. Mnemosyne has been acknowledged as heterogeneity than linearity, by extension, been activized as an archive operating the reconfiguration of our history. In terms of Mnemosyne, city is close to us, but at the same time, is far different from reality. It is close, because it is based on where we live. But at the same time, it is far different, cause it has a potential to reconstruct our reality. In this context, this study noticed recent artistic practices in Korea focusing Seoul as an archive, and tried to find alternative way of reading cities. Many artworks expressed the process of forget, memorize and reconstruct the memories of Seoul, rather than just memorize them. These memories present various visual variations by being expanded to social memories, recreated and ambiguously juxtaposed with diverse layers of realities.
