Fractal geometry is a concept that has attracted the attention of architects and designers all over the world; this is because modern architecture tends to be inspired by nature, and natural elements are primarily the source of inspiration for designers in fractal geometry, the inspiration of nature and natural elements is an important task. Naturalism is likely related to the current era. An interesting and important point is that Iranians have paid a lot of attention to the nature and utilization of natural elements for a long time ago; and this interest is shown in a variety of ways in their life, such as using fractal geometry in different shapes and forms of inspired elements from nature. This usage is The highest point in Bazaars, Mosques, Kar-bandi format, Moqarnas, and Shamseh. Because of this, this research tries to investigate the utilization of fractal geometry in Iran's Bazaars and Timcheh through sample analysis with field and library studies by analytic and descriptive methods. This research wants to answer the following questions: Is there any consistency among fractal geometry conditions? Could it be generalized to society? If the answer is yes, what are the methods of updating and expanding it in this situation? Therefore, after some accurate investigations, we will conclude that the traditional usage of fractal geometry in Iran's Bazaars and Timcheh can be modernized and expanded. Moreover, some methods to achieve it are presented.
