This thesis investigates the phenomenon of urban scars in Novi Sad through an architectural and urban analysis of five representative sites characterized by distinct forms of degradation. The theoretical framework draws on the concepts of urban leftovers, brownfield, greyfield, terrain vague, and urban void, through which a typology is established and classification criteria are defined. In addition to historical and spatial analysis, a survey was conducted to examine citizens’ perceptions of these sites as potential carriers of urban identity. The study argues that urban scars should not be understood as a final stage of decay, but rather as dynamic processes shaped by institutional decisions and societal attitudes toward the built heritage, thereby foregrounding the responsibility of the contemporary city toward its own historical layers.
