Flagpole supports were stone structures used in temples, symbolizing the temple or hanging a Dang on the Danggan to announce event, and played a crucial role in supporting both the Dang and the Danggan. The flagpole supports are not merely stone structures but hold significance in their relationship with the temple itself. Currently, around 86 of these flagpole supports remain in Korea. Despite a considerable number of flagpole supports still remaining, research papers and materials on the subject have been scarce, except for recent survey reports, precise measurements, and Um Ki-pyo's “A Study on the Dangcan and the Dangcan-Jiju in Korea.” While art historical research is abundant, architectural studies are still needed, and this study aims to fill that gap. First of all, the status of Flagpole Supports was identified based on the field survey, a precision survey report and other data were used, and an analysis study was conducted. This study, therefore, focuses on (1) the current status of the altered flagpole supports, and (2) the classification of the types of jointing, categorizing the methods of flagpole support jointing into five types based on the presence or absence of a base. Therefore, this study aims to identify the current status of flagpole supports and, through analysis, classify the jointing methods to provide foundational data for future research.
