Persian garden design is one of the main elements in the architecture and landscaping in Iran and the whole lands influenced by the Iranian culture. This phenomenon has always been present in Iranians' life and they have had a close connection to this ancient tradition. Hence, it can be said that Persian garden design is one of the most crucial features in shaping Landscape, in particular, and creating built environment, in general, throughout the Iranian history. In this research, we don’t intend to valuate the Persian garden design or favor it in Landscape architecture. Our purpose in this study is to seek our identity in Landscape architecture through examining space elements in the Persian garden design. How this space in the physical structure of Persian garden is grasped by viewers or whether the physical structure of this phenomenon still persists in the collective memory of Iranians is not the point to be scrutinized by this research. Any answer to these questions requires probing into other fields. The research methodology in this study was descriptive and analytical and we have collected data in field and bibliographic investigations. This study shows that the Persian garden design is a systematic space shaping with respect to all phenomenological aspects of this concept, and it can be described as a worthy system in Landscape architecture and a pioneering approach in designing and organizing built environment in connection with nature.
