Despite the international value of the Sheikh Lotfollah monument, no complete documentation of its changes and interventions has been carried out so far. Revealing hidden and undiscovered aspects of the form and function of Sheikh Lotfollah can identify any inappropriate interventions done in the past. On the other hand, it can pave the way to preserve this building for posterity.Research objective: This article aims to display the transformations of unique and little-known features of Sheikh Lotfollah for the first time.Research method: This research attempted to present the transformation process of this building by analyzing related descriptive and visual documents in the order of the year. In addition, some of the unwritten features of Sheikh Lotfollah were documented by interviewing people who had been involved in its conservation from the past until now. Moreover, the main part of this research was done with a detailed field survey of each part of this building. Ultimately, all the analyses were implemented on the maps.Conclusion: This research revealed that some sections of Sheikh Lotfollah were separated from it over time and dedicated to other functions. Consequently, the changes in the access point to the building brought about changes in the original plan and form of the building.
