The pattern of single pagoda-image hall, typical site design of Buddhist temples of Buyo period (538-663 A.D), was not a fixed pattern, but was in a process of continuous change. This can be identified by the change of size and material of pagoda, relative dimension of cloistered corridor, and arrangement of belfry, sutra repository, and lecture hall. The examination of such changes enable us relocate the periodical positions of the sites with unknown dates, and understand the background of the changes.
