A Study of the Impact of Roads in the Formation of Structural System of Tabriz during Ghajar Dynasty

Morris believes that the townscape of the Islamic cities is affected by two sets of early and late factors. The early factors relate to heritage of Arabia and the Ancient Mesopotamia, and the late factors concern with the answers to the requirements of Islam. Being included in both factors, the roads and passageways have been affected by and also effective on the townscape. This paper intends to study the factors that were effective on the formation of city roads during Ghajar Dynasty, surveying the bilateral effects of them on the formation of urban structural system. To achieve the mentioned goal, the study attempts to analyze structural features of Tabriz in the Ghajar period, highlighting the impact of roads and passageways on the quality of the space-communication of city.The study shows that Tabriz city inherited the changes of periods before the overall body of the city during the Ghajar Dynasty. The two major roads, namely the Silk Road and the road from Baghdad to Rey, were among significant factors in the formation and development of some major structures such as Bazaar, and governmental complex and developing of residential districts, and consequently the expansion of inter-city road frameworks. All these changes along with the improvements in Ghajar Dynasty caused a closely-woven, practical and cohesive framework of roads to be made. Being located in a hierarchy and attracting architectural and urban factors in the best way, the framework of roads addressed the requirements of city communication.
