Revisiting Missing Identity Ring of Iranian cities (A spatial Temporal Analysis of square Elements in Islamic Architecture and urbanism)

From long ago, square has been considered as a space for performing area of cities, and it has been a factor determining the identity of cities through its design and structures. However, with the growth of cities and arrival of modernity management challenges are facing cities. Accordingly, cities have gradually changed into a place for predicting different types of technological, conceptual, and social solutions. These factors have embedded their objective manifestation in the body of Iranian cities along with Persian – Islamic architect and urbanism and put in place a new form of urban spaces. In the meantime we are witnessing that past function of spaces such as squares previously used to be considered as an open space and an element indication the spatial – physical coordination of activities, has changed and gained new appearances. The present paper seeks to investigate the factors such as changes in visual and motor space, new civil relations and stimuli speed in three steps. Including: 1- ideal space, 2- movement space, and 3- visual space in forms of square as an element for gathering, square as an element for passage and square as a missing ring, Moreover, factors affecting the survival or destruction of this missing ring of Islamic architecture and urbanism will be analyzed. Also identify – causing factors in spatial analysis of square and the role of theoretical knowledge in understanding instances of Identity will be making clear.
