The present article is an analysis of the formation and evolution of the city of Songhor in Islamic times. This research is descriptive-analytical in terms of purpose and method. And to collect the required data and information, library-documentary studies and field visits (observation, testing and interviewing) were used. Among the archaeological evidence and historical documents examined in this study include: pottery, gravestones of medieval Islamic times, religious and non-religious architecture, and springs and sanctuaries. Its field data is recorded and classified by time period. Reading and reviewing historical and archeological information related to the city of Songhor reveals the cultural and historical identity of the city during the Islamic period. The results show that Songhor city is based on fundamental elements such as: the mosque, government building, monuments, traditional market, neighborhoods and city fence which during Islamic history are related to specific hierarchy in relation to social, economic needs. Religious, political and city fix

Ancient cities have always possessed inherent distinctions from contemporary cities, which are evident in their physical structures and overall layouts, allowing them to be easily differentiated from their modern counterparts. These distinctions, influenced by economic, political, cultural, and social conditions, have resulted in varying degrees of change in the urban structure and have given rise to two types of urban growth. Organic growth is characterized by a continuous and coherent expansion that prioritizes form in relation to function, in stark contrast to the fragmented and discrete nature of global cities in the modern era. This study seeks to address whether it is feasible to apply the characteristics and developmental patterns of ancient cities in today's world by examining the evolution of urban form throughout history up to the present day. Alternatively, can a favorable outcome be achieved by integrating certain characteristics of ancient cities into contemporary urban environments? Based on this objective, the study explores the evolution of urban form across three historical periods - pre-Islamic, post-Islamic, and the modern era - with a particular focus on the establishment of governmental centers in the central desert of Iran. The comparative method of induction is employed to discuss the subject matter in line with the research assumptions. The findings indicate that the first and second hypotheses have yielded more significant results in a greater number of unsuccessful experiments. Conversely, the third hypothesis has been more successful in a wider range of experiments with diverse outcomes. Moreover, considering the success rate of 0.100 and the absence of unsuccessful experiences for the Kerman experiment, it can be argued that this hypothesis is relatively superior and preferable for assessing the success rate of related projects.
