This paper aims at proposing constructional intention and aesthetic consciousness in the architecture of Jajang-temple, which was originally built by the great monk, Jajang in 7c. The results are as follows : 1) The layout and form of buildings in Jajang-temple were remarkably followed the situations and shapes of natural rocks related to Gumwa legend about the original establishment of the temple. 2) As natural rocks were penetrated into both the inner and outer space of buildings and so artificial skills were more or less restrained, it seems to be short of geometrical regularity, symmetry and formal integrity. 3) However it can be said that these architectural treatments were based on the aesthetic consciousness, so called In-Cha and Jol-Bak, which were conceived by intellectual elites in Chosun dynasty.
