Iranian architecture started to develop at the beginning of the Pahlavi era, and a historical gap happened between what was identified as traditional and contemporary architecture. Meanwhile, some efforts were made to establish a connection with the identity of Iranian architecture, which this confrontation has been extended up to now. This study aims to explain the factors affecting the continuity of architectural Identity to reconsider how the Identity of Iranian architecture started to extend and continue during the first Pahlavi era. The qualitative research method, an interpretive-historical type, was adopted for this study, and to deal with the Identity, library resources have been used to analyze the selected buildings in Tehran city as a case study by determining the relevant theoretical framework using the bibliographic research, and both field and visual interpretations. The continuity of Identity in architecture initiates through the objective encounter with the building's physical structure, through its physical characteristics and recognition. Then it will be realized by the audience's vision according to the thought processes and eventually by comprehension and cognition within the life current, events and determining its location. The Identity of Iranian architecture during the first Pahlavi era has been continued by reviving the nationalistic and ancient styles. This has influenced the idea of architecture relying on Iran's historical and cultural memory. Despite their representation in new functions, some of these identical concepts have continued.
