Neighborhoods have historically been the social habitat of city dwellers. This social unit, which was considered as a cornerstone of Iranian-Islamic society, has demonstrated the structure of ancient Iranian cities in a distinctive way. Various political, administrative, economic, and socio-cultural factors have led to the formation of the neighborhood's physical space in the city, of which social and cultural factors are of particular importance. Today, due to some shortcomings in providing services, some of the historic and old neighborhoods of cities have been intervened by urban management. If these interventions are carried out without considering the memories and affiliations of citizens and their mental needs, it will lead to rapid developments in historical fabrics and the erasure of the identity of cities. One of the platforms for changing the shape of these neighborhoods is urban development plans. This study aims to evaluate the changes in the identity and physical characteristics of Sarshoor neighborhood based on comprehensive and detailed plans and focuses on the changes in the characteristics of the neighborhood. This study is practical in terms of purpose and qualitative in nature based on thematic analysis. The strategy used in this research is inductive. The data collection method is both library-based and field-based. The findings of this study indicate that with the interventions of urban development plans in different years, the residential, tourist, and market characteristics of this neighborhood have changed and have gone out of balance. The residential characteristic of the neighborhood has been severely weakened due to the departure of native people from the neighborhood, the decrease in the sense of belonging, the increase in land and goods prices, heavy traffic, and the increase in residential users.
