Became. So, the problem of intrinsic movement and perception of space in architecture will be the main topic of this research. The main goal of the present study is to investigate the levels of space perception in the portico of Allah Vardi Khan based on the concept of the essential movement of Mulla Sadra. For this purpose, the levels of perception of space in the portico of Allahvardi Khan have been examined. This is a qualitative and analytical-descriptive research. The research strategy is a case study with an interpretive approach. This article discusses the comparison of movement and perception in philosophy and architecture by analyzing the perceptual experience of the observer in the portico of Allahvardi Khan. The results show that the spatial hierarchy in the portico of Allahvardi Khan, the lack of variety of materials in the interior of the portico, and the human encounter from the entrance to its center lead to the improvement of the sensory perceptions and the spatial experience of the pilgrims from the portico.
