The subject of geometry and proportions has been regarded as an issue which has a close relationship with architecture. Since the entire universe, living beings and the human geometry can be seen clearly, that’s why our unconscious essence has accustomed to these proportions whereby reflection of this mentality can be seen in the architect’s hands and thought in the architecture. It can witness a close linkage between nature and architecture at different levels in Iranian architecture which the linkage at architecture geometry has been regarded as one of these levels. Iranian geometry using plant and geometric forms in Islamic buildings seeks to prove a special continuity in the life to plant and human world. This continuity in the world of geometry has been known with fractal geometry. The present research seeks to examine dimensions of fractal geometry in Iranian architecture and motifs. In following, an attempt is made to examine what the fractal means in Iranian architecture and clarify the motifs and decorations of Iranian architecture after defining the issue of fractal, fractal geometry and fractal in architecture.
