Urban spaces are important for communities as places to practice different activities that help meet users' needs. Therefore, the study aims to examine the results of prior research using space syntax to understand the relationship between the spatial configurations of spaces and users' behavior, as well as its impact on improving the use of urban spaces. So, the paper began with a quick summary of the theory's foundational concepts. “The social logic of Space" by Bill Hillier and Julianne Hanson (1984) and “Space is the Machine" (1996) follow. Then, if it was essential, current publications and studies that had a significant influence on the theory were referenced. One of the main study questions in space syntax research has always been how to describe and predict socio-spatial experience. by analyzing Trafalgar and Old Market Square and studying the role of space syntax theory in enhancing these two squares. Results, there is a relationship between human behavior and spatiality in those two Squares. From the foregoing, it is clear that Space Syntax is a vital tool in understanding and predicting the movement and user behavior within urban spaces, which is recommended to be used to study and enhance the performance of urban spaces. In conclusion, this paper presents a theoretical basis for understanding and facilitating the application of space syntax in urban space.
