This article focuses on the role of architecture and art in regards to the picture of Hiroshima as a specific place of remembrance (lieu de mémoire) for Japanese society. While analyzing those aspects, not only the form and design were considered, but also the political situation in the 1940s and 1950s, as well as social moods and expectations that shaped the postwar Japan. The paper bases on a case study of an architect Tange Kenzō and Noguchi Isamu, also an architect and artist, who had a great influence onto the creation of Hiroshima Peace Memorial Park.
