The Stone Pagoda at Mireuksa Temple Site, Iksan, built during the reign of King Moo(武王) of Baekje(百濟), is one of the earliest stone pagodas in Korea. The main feature of the Stone Pagoda at Mireuksa Temple Site, Iksan is the technique of constructing the pagoda body using a technique of constructing stone structures that is difficult to find in China or Silla during the same period. In this study, we inferred that the origin of the Post & lintel construction technique of the stone pagoda of Mireuksaji Temple in Iksan came from the Post & lintel construction Stylobate of Baekje. As a result of comparing the part composition and joining method of the pagoda body and the Post & lintel construction stylobate, it was confirmed that the Post & lintel construction stylobate influenced the construction technique of the pagoda body. In addition, differences in the way the Post & linte construction technique is applied depending on the location of the pagoda body of Stone Pagoda at Mireuksa Temple Site, Iksan were inferred. This study is significant in that it clearly reveals the origin of the unique construction technique of the Stone Pagoda at Mireuksa Temple Site, Iksan.

This study aims to classify the architectural formation of the Stylobate of and Staircase types of Post-Lintel Construction in Backje style and Silla style and also to figure out their specific elements by periods and transformation characteristics. The scope of this study was restricted to architectural remains between the Three Kingdom period and the Goryeo period. To progress the investigation, the study classified remains in a similar type by period and type, and then and analyzed its character based on formation method and specific factors of subsidiary materials. As a result, its type can be classified as Backje type(Ⅰ), Silla type(Ⅱ) and Mixed type(Ⅲ). Regionally, it is found that Woongjin, Sabi and surroundings in the capital of Backje, Gyeongju and main towns in the capital of Silla, and Gaeseong and main towns in the capital of Goryeo. In particular, type III has the characteristics of type I and II simultaneously, which has one or two layers Jangdaeseok stone between the foundation stone of stylobate and plate stone, and tends to be decorative when Taengjuseok stone is installed. For types of staircase, it could be classified as 6~7C Backje type(Ⅰ), 7~9C Silla type(Ⅱ) and 9C Mixed type(Ⅲ) according to the formation method of Somaetdol (banister of stone stair). And from the 9th century on, decorated Somaetdol stone type(IV) of 1/4 circle shape began to appear. The common feature of stylobate of post-lintel and staircase is that it became simplified, abbreviated and decorative. It seems to be intended to secure simplicity of construction or structural stability.
