According to archeological sources, there was religious diversity in the Parthian period. The Parthian kingdom made it possible for various religious followers to practice their religious rites and ceremonies freely throughout Parthian empire. As a result, due to the various ethnic and religious groups, different methods were created in the construction of tomb buildings. The construction of the tomb as a kind of memorial structural design has always attracted the attention of the elite of the society. Burial buildings were a reflection of the power of the deceased in the political, religious, economic and social structures of society. This type of building has always been respected and sanctified by the people, and through its connection with the identity roots of the society, it led to the formation and development of the architectural traditions of the tomb throughout history.
