Individuals' experiences related to space create their spatial memory. The signs that are admitted as symbols, monuments and indicators transferred by the society are reflected in the collective memory of the space and define the common identity. In this context, interventions in urban space affect user profiles, activity diversity, the meaning attributed to space, and it causes the user's perception of urban identity to change. Within the scope of the research, Azapkapi, located in Karakoy sub-region of Istanbul province, was selected, and it has been an area where many socio-political and spatial strategies have been concentrated since the 2000s. Transportation projects in the area diversified the user profiles, activities such as the reorganization of coastline and the fishing market changed the land use and user perceptions. In this sense, to realize the changing meaning of the area in the collective memory, literature review and text analysis were carried out on newspapers published since the 2000s. To determine today's perception, the user profile (age, gender, education status), the place of residence, the frequency of use of the area, how they define the space, for what purpose they use it, the problem and potential definitions were questioned with a survey study. As a result of the research, it was concluded that the meanings that local and daily users attribute to mega projects and places in the district differ.
