Abstract
This study aim to clarify the way of spatial composition of Tongdo Temple by diachronic analysis. The way of spatial composition was clarified through the analysis of built in architectural system in three periods. The result are as follows; 1. Spatial composition of Tongdo temple was changed in three period that it were establishment period, 1300s, and 1700s by the transition of meaning structure occurring the transition of spatial composition. 2. It was found out that the wat of spatial composition was three through the diachronic analysis the transition of spatial composition in Tongdo temple. 3. Juxtaposition as a way of spatial composition found out through the diachronic analysis is equivalent articulation of three sections; an upper, a middle, and a lower section and polyaxis or polycore in the each sections. Fusion is heterogenetic minglement mingling different kind of buildings and conjugation conjugating different kind of decorations. And accumulation of layer is mutilayer laying different time of layer and multi aspect aligning different kind of aspects since the temple's establishment.
