Studies and reports on buddhist temples in Goryeo dynasty are rarely in the present situation. At this point of time new excavational reports and historic records offer many materials to understand a architecture in Goryeo period. Especially, temple site have various transitions, it is of great value to study. This article attempted a restorative study of a location, function, spacial arrangement, structure, building age is based on a measure and transition of temple layout that is based on the excavational result and related historic documents about Godal temple site in Yeoju. Godal temple site was a representative Zen buddhist temple in Goryeo Dynasty. It was difficult of access by watercourse because it was located in an inland in the upper Han River. Archaeological research and historical records has reveals that the temple was constructed with a minium of four levels[six terms]. We could recognized the central site of temple and buildings were constantly established, enovated or collapsed. It has went through many transition according as it encountered new sects and doctrines. Also it should perform various functions and overcome given conditions. Ultimately it let see greater diversity in the spacial composition, and layout. That is to say it were planed several separate areas, each was consisted of main buildings, once again was integrated into one temple.

The architectural characteristics and historical positioning which the historical architecture will be understood better through collecting results from researches which was done on various points of views and positions. Therefore, a study on the layout of the main palace of Goryeo Dynasty also becomes a prerequisite for understanding the architectural characteristics and historical positioning which it possesses. However, the reality is that as the results from the excavation and preceding researches were not integrated together, the understanding of the layout of main palace is remaining on a partial and conceptual level. Therefore, this paper attempted to review in overall the restoration of the layout of the main palace of Goryeo Dynasty using historical documents, precedent researches, excavation maps, topographical map and cadastral maps. Consequently, it was possible to confirm the name of some of the ruins and restore the location and layout of other buildings. The result of this research presented above, will become a basis for understanding the layout of the main palace of Goryeo Dynasty in more realistic and way. Furthermore, it could be used as a fundamental data for related researches.
