The reciprocal relation between historical, economical and social developments and urban space also exists between urban memory and urban space. Therefore, the analysis of the dialectic relation between urban memory and urban space and investigation of environmental perceptipon and their representation in the memory provides substantial potentials for understanding the abstract repercussions of memory on urban space beyond conceiving it only as a physical asset. There are many questions on evaluation of the environmental perception and analysis of the representations on memory; how is the knowledge on urban space represented through cognition, what are the processes of that, what are the personal restrictions to express the experiences and perceptions on urban space, what are the convenient methods and tools for evaluating all of them. These questions have been still argued. However, thinking on "how" the truth is formed, or "how it left its mark" or "how it reproduced the meaning", rather than "What the truth is" will provide opportunities to reconstruct the historicity. Thus, in this study, the representations of the urban space on urban memory is examined through the case of Mersin by using the oral history method. The reciprocal relation between urban space and memory is scrutinized through oral history interviews with inhabitants of Mersin, and the improtance of aforementioned relation and the problems embedded on urban space in relation to memory is discussed.
