Activities intended at increasing the accessibility of offers connected with urban growth and efforts and pragmatic practices targeted at boosting community contact through the usage of common areas contribute to cultural integration in the urban context. Bag Bazar Street is one of Kolkata’s three main streets, known as the grandmother road in ekantoporibar (joint family), making it an excellent case study site. By developing and assessing ideas regarding urban mobility characteristics and linkages across time, syntactic space analyses aid in the examination of diverse historical sources to build a coherent narrative of urban topology configuration. In a quantitative study of urban space and space syntax, enticing prospects as an exciting development of spaces use the city plan as the initial stage for investigating the historical relationship between the urban setting and urban life. The significant features of the axial line are with utilizing the argumentation of extrinsic spatial features in space syntax. DepthMap, open-source software for studying the visibility of urban core, was used in this study. The utilization of an axial map with a connection map is to frame basic facts in the study. Any strategy to revival or smart city development necessitates a full grasp of the spatial factors and stages that characterize our urban communities, as well as the link between the two. Consequently, this research uses axial analysis and visibility graph analysis to validate the degree of functionality of Kolkata’s Bag Bazar street over time as an input for digital preservation. The paper identifies the period having transformation for each attribute. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
