The object of this study is concerning about the structure of poetic space. In general, poetic space shows the method of reflecting on the reality of present circumstances faced by the poet. From this aspect, this study undertakes to analyze the phenomenon of the poet`s personal experiences with space, and to clarify the leading space of his awareness through his structure of imaginable space. The phenomenon of space as experienced by Mr. Jong Sam Kim has been reviewed in two phases ; one, experiences during childhood, and the other those incurred during the Korean war, which resulted from the division of our nation. As a result, the phenomena of non-existence and devastation of space is noticeable. As a background to such phenomena, he became aware of the nonexistence of space due to his experiences with death encountered during childhood, and aware of his lost hometown, along with a sense of devastation, due to the nation`s division and subsequent conflict. The poet`s imagining structure, due to this awareness, has a contrasting double structure, forming reality and illusion as the exterior and interior, respectively of living space. Discontinuation and continuation in reality and illusion constitute the basis of the space structure of the poetry of Jong Sam Kim, generating negative awareness with respect to real space and a limited means of confrontation. In real life, it has been found that Jong Sam Kim frequented places where full of artistic illusion, or poor spaces where alienated persons lived. The poetic inner spaces of Jong Sam Kim show that his unique aspect on spaces is generated from juxtaposed structures of reality and illusion. His intention of overcoming the reality of a barren castle and the hopelessness of existence in limited time is realized filled in the symbolic representation of material things and music by means of structures juxtaposing reality and illusion. The basic poetic sentiment of the poet Jong Sam Kim lies in his awareness of peace and pity for alienated thins and peoples. The awareness of peace filling the spaces of poems by Jong Sam Kim forms the essence of his whole focus on recovering the original relationship between people and people, and between people and things, all suffering in this world.
