This study analyzed the spatial hierarchy of Hyangkyo architecture. Hyangkyo was built on the basis of Confucianism. The results are as follows; 1) The spatial hierarchical construction responding to the site. The arrangement style of hierarchical construction changed according to the site. This is the reason that the hierarchy of Confucianism has the relationship of the upper class and the lower class, high and low of position, high of right and low of left, and the theory of division based on topography. 2) The hierarchical construction responding to the arrangement style. Buildings were hierarchically constructed according to the site of the architecture. This is the result of hierarchy. In conclusion, the spatial hierarchy means that Hyangkyo architecture had been built according to an order on the basis of Confucianism.
