Gaetaesa Temple is a royal temple associated with King Taejo Wang Geon of the Goryeo Dynasty, serving as aJinjeon(眞殿). The recent completion of the 6th archaeological survey revealed the core and living areas of the temple. In thecentral area, structures such as the gate, main hall, East-West buildings and Jinjeon were identified in four tiers at the inclinedsite. Presently, Gaetaesa Temple exhibits traces of the early Goryeo period, and various interpretations regarding the nature ofthe excavated buildings have been proposed in relation to Gaetaesa Temple. The objective of this study is to derive thecharacteristics of each structure through a comparative analysis of the temple's architectural features with those of the sameperiod Buddhist temples. Although Main hall shares similarities in scale and layout with the same period Buddhist main halls,the presence of stone flooring suggests the possibility of it being a Jinjeon. The East-West buildings on the northern part ofthe Main hall exhibit the potential for corridors and pavilions, with indications of a possible Bangjang(方丈) in the easternsection and a Amitabha hall in the western section. The northernmost Jinjeon, typically situated in the northwest, also presentsthe possibility of being located due north, making it the most suitable form and scale for excavation, including the entire vicinityof Gaetaesa Temple. Therefore, Gaetaesa Temple has the potential layout of a main gate, main Buddha hall, eastBangjang-west Amitabha hall, and a Jinjeon.
