The importance and role of mosques in Islamic societies, including Iran, is not covered by anyone, and no doubt, the more the number of mosques and mosques are, the more Islamic culture will be enhanced and strengthened. The Islamic Revolutionary Guards Corps (IRGC), as an institution that has always been at the highest levels of strengthening Islamic culture in the community, has so far contributed to the construction of mosques and the establishment of a mosque culture in society and among the youth and citizens. The construction of mosques, the insistence on promoting the culture of the mosque and the objectification of the functions of the mosques, is one of the hallmarks of the influence of this holy institution on strengthening Islamic culture from the mosques and institutionalizing it. In this paper, the role of the Revolutionary Guard Corps in constructing the mosque Taraz and the institutionalization of the mosque's culture in society should be examined based on the descriptive-analytical and library methodology. The results of the research have shown that the Revolutionary Guard has taken steps to institutionalize the culture of the mosque of Taraz through the establishment of the central mosque culture and the participation in the construction of the mosques and the comprehensive emphasis on this issue since the beginning of the revolution. The implementation of the duties and functions of the Revolutionary Guards with the functions of the mosques shows the two-way and evolutionary relationship between them.
