However, while there are not many, some architectures have rafter end header in the square shape. The aim of this study is to examine the square shape cases of rafter end header with special reference to stone structure. As a result, among stone structure related to Bangyeon, the majority case is seen at Palgakwondang type Seungtap. It was shown in the Seungtap of monk of Gusanseonmun school in the later Unified Silla to the early Goryeo period that succeeded Seodang Jijang.
