Abstract
Religious architecture in the Gwangju and Jeonam regions played the role of local culture, and in particular, cathedral architecture maintains a consistent religious context and seeks to integrate with the local community. This study is to investigate and analyze the overall data to find out the characteristics and meaning of the Eucharistic adoration, which played a central role in the religious aspect and the space in the cathedral, and used it as basic data for the study of local cathedral architecture. The Eucharistic adoration was activated starting from the time when the Eucharist storage room was placed in the Middle Ages, and in 1979, when Pope John Paul II published a letter, and Bishop Na Gilmo of Incheon introduced the Eucharist, the Eucharistic adoration movement was activated in parishes across the country. However, regarding the Eucharistic adoration, a way to use its spatial meaning and religious use is still unknown, even to its believers. The Eucharistic adoration of the cathedral contains the main spiritual function of managing faith rather than the functions of mission, fellowship, and office work. An approach which composes the liturgical spaces in various architectural planning methods is necessary, but the fundamental and religious meaning must not be abandoned.
