Introduction: The Tarazabad caravanserai is situated along the main Rey-Kerman route, near the city of Meybod. In this caravanserai, various elements with specific functions have developed in response to needs, each contributing to the sustainability of the complex.

Methodology: This study follows a field and library research approach, adopting two general methods. First, each of the caravanserai components was examined individually. Second, the entire complex was assumed as a single integrated whole. Instead of focusing on the components, the focus has been on the interrelations between them in shaping the entirety. Subsequently, the structure of these buildings and their meanings were investigated within the context of the intellectual traditions of Iranians.

Results:One of the key subjects in structuralist theory is the understanding of dualities. In the Iranian culture, paying attention to such dualities is of particular importance. According to the building’s plan, such dualities must be taken into account, followed by examination of the symbolic significance of each, and ultimately, the structure of the caravanserai must be analyzed within the obtained symbolic system. The criteria include: "Indoors and outdoors”, “core and periphery”, “south and north” directions, and the symbolic opposition between the elements of “water and fire”.

Conclusion: The conclusion is that in mythological cosmology, any inhabited space is a reenactment of the primordial act of creation by the gods and, in its form and structure, follows the same symbolic system. This imitation and repetition are not merely aesthetic or decorative aspects, but they are a cosmological necessity. Through this, the formation and continuation of life become possible. As a standalone cosmos, the Tarazabad caravanserai reflects this symbolic system perfectly and beautifully.
