Investigating the relationship between the elements of the Islamic Iranian city and the physical structure of historical contexts (Case study: Birjand)

The ancient Iranian-Islamic cities have formed an integrated and stable system by establishing a physical and spatial connection between the economic, social, administrative, cultural and environmental components. Among these features, division of spaces, group and social structure of neighborhoods, physical and spatial cohesion of the bazaar and the Grand Mosque with each other. Therefore, the present study aims to investigate the relationship between the elements of the Iranian-Islamic city such as human-centeredness, security, the principle of hierarchy, naturalism and boundary with the physical structure of historical contexts to study this relationship in the historical context of Birjand. The type of the present study is analytical-interpretive and the data used is the information on the characteristics of the Iranian-Islamic city extracted in historical books and writings and the current map of the historical context of Birjand, which is drawn in GIS ARC software and the results of this comparison. Has been analyzed. The results showed that based on the relationship between the historical and cultural characteristics of the texture with the neighborhood-centered element, the relationship between the geographical elements of the texture and the element of naturalism, the religious function of the texture with the human-centered element was in line with the Iranian-Islamic model. However, based on the principle of local hierarchy and continuity, due to the construction of new streets and the loss of communication between alleys, as well as changes in the type of building, the texture has changed and has moved away from the Iranian-Islamic city model.
