Cities are prominent signs of civilization in every nation. The signs, old symbol of ideas, customs, relationships and interactions of people have played a role in the formation of cities and intertwined a set of environmental, geographic, climatic, traditional and religion combination. Historic cities in Iran are the most valuable cultural heritage that expresses the dynamism, vitality and symbol of urban life. Architectural and urbanity of ancient Iran includes principles that have been manifested in the heart of the tradition. In recent decades, due to unbalanced expansion of cities and discontinuity of spatial organization, and arrival of new technologies, globalization and the space density, traditional city is far from its truth and it has created challenges for traditional urbanism and modern urbanism. Therefore, the main content of this paper includes spatial structure approach, respecting the history and concepts of Iranian traditional city.

Searching climatic patterns and patterns of access based on traditional experiences can lead us to achieve harmony with the environment. The necessity of understanding the concepts of traditional city, cultural features, indigenous and historical context and criteria for recognition for structure can result into creation of objective models. This research tries to achieve the traditional Iranian pattern for design of historical context in Miyaneh city.
