Abstract
The purpose of this study is to reveal the utopia concept of Maitreya beliefs inherent in the building of the temple Keumsansa. In order to grasp fundamental order and concept of religious architecture, it is needed to understand internal viewpoint of religion which is unrealistic and idealogical phenomenon from the belief organization. As a result of this study, the relationship of Maitreya Hall as representation of Maitreya-Hasang belief and Bangd$\breve{u}$ng commandment-pulpit representation of Maitreya-Sangsang belief is based in the nondual understanding. And, the meaning of Maitreya beliefs inherent in My$\breve{o}$ngbu Hall is founded in the role of mediators between Maitreya and Buddha.
