The article considers the theoretical foundations of the emergence of geometric singularity of the spatial form of urbanized territories in the context of translating the specific vocabulary of formation and the norms of cultural tradition. A comprehensive consideration of the problems of preserving and developing the historical appearance of the city, as well as the issues of solving the problems of forming a modern urban environment, forms the basis of the meaning and content of the article. The methodology for studying the phenomenon of geometric singularity of the spatial form of urbanized territories in the context of the historical environment of the center of the Siberian city is the basis of analysis and criticism as specific forms of activity and functioning of the urban community. The study is based on various types of ideas about the organization of the structure of external relations, understanding and designing the mechanisms for developing their own types of activities and urban environment, which ensures the normal development and regeneration of the architectural form. The main stages of the formation of urbanized territories are outlined. The problem of formation of the concept of singularity considering preservation and development of urban identity, as well as formation of modern urbanized environment is considered. The methodology for studying the mechanisms for forming unique units of the original image of the cultural and historical environment is based on the study of the geometric identity of spatial forms of co-organization of urban communities. The methods of geometric singularity of spatial form of urbanized territories considered by us in the context of translation of specific vocabulary of formation and norms of cultural traditions of historical environment of cultural and social center of the city allow carrying out described operations on various types of initial and operational data from deployment of whole spectrum of parameters to their comparative assessment and obtaining indicators of compliance of studied structure of composition with given standard. The results confirmed the existing theoretical provisions, thereby showing the effectiveness of the study.
