The survey of Sardasht ancient ways and its related facilities in the Islamic period Based on the archaeological texts and evidence

West Azarbaijan is considered as one of the key and important areas in the archaeological studies of Islamic period of Iran (especially in the Ilkhanate and Safavid periods) due to its connection with Mesopotamia and Asia Minor, which, unfortunately, was not well-considered by archaeologists. Sardasht is geopolitically and strategically oriented as a canal that is located on the route of North West communication network to Iraq and Syria.Accordingly, the main questions are:1- What are the archaeological evidence in the context of the communication ways of this region? 2-What is the influence of the position of Sardasht on the formation intra-regional and extra-regional Northwest ways?The main purpose of this article is to reconstruct ancient ways of Sardasht. Research method in this study was descriptive-analytic(a combination of texts, archaeological evidence and GIS).In describing ancient communication routes of the area, the authors defined their fieldwork by scrutinizing the following principles:1-Reviewing historical texts and library studies in relation to the topic concerned 2: Exploring and studying the bridges and caravansaries of the region as factors associated with commercial ways 3:Surveying the archaeological evidences of old roads and Surveying the ancient sites and analyzing their location in relation to the proposed routes,4: Using GIS analysis and integrating it with archaeological evidence and interpreting satellite images.Archaeological evidence includes 5bridges,2 caravanserais, remains of roads, a mass of rocks with the possible use of a guide, and a large number of Islamic and historical sites. According to the results, there are two main connecting passages in Sardasht, which have been used for archaeological evidence from the first millennium BC to the late Qajar period.The Alan crossing in the south of Sardasht, which is connected to Kukhi Kurtak crossing on the northwest side, has been the main route and the passage of Qasma Rash in the west as a secondary route,including Sardasht's routes to Iraq, and in particular Sulaimaniyah.
