The mosque is one of the manifestations of Islamic art and has long held a special place in Muslim societies, serving as a cultural, social, religious, and even political hub. It has historically been one of the most important centers of social interaction and one of the most prominent urban elements. However, over time, various factors—such as prioritizing form over meaning, lack of sufficient knowledge and awareness of Iranian-Islamic architecture and culture (Especially in the construction of traditional buildings like mosques), and the insistence on blending modern and traditional architecture without a proper understanding of their foundations—have led to the decline of this role. As a result, the mosque has been reduced to a space merely for performing prayers or holding mourning and occasional celebratory ceremonies. This deterioration can negatively impact social interactions and, consequently, social vitality. In today's world, every society, drawing on its own culture and diverse elements, seeks to enhance social and cultural engagement among its members, thereby boosting collective enthusiasm and vitality. Therefore, there is a clear need to change the perception of mosques and to revive their role, identity, and function in contemporary conditions in order to reestablish the historical connection between mosques and people. Thus, through field and library research and using descriptive-analytical methods, this study first examines the reasons behind the decline of mosques in the modern era. Then, by posing questions such as: How can the past relationship between people and the mosque be restored using today's standards? And what are the principles for designing a mosque today, considering societal needs? We aim to propose strategies for revival. Ultimately, we conclude that restoring the mosque's former role and status requires proper site selection and a form of architectural design that aligns with the culture and demands of the present time.
