In Korea during the enlightenment period, there were very active changes in almost all areas that made up the era, including politics, economy, society, and culture, and these changes were no exception in the religious field. This study aims to identify the characteristics of architectural elements of compromising style of Korean traditional cathedral architecture, especially in the case of Nabawi Cathedral, a representative compromising style of Korean traditional cathedral, which appeared in the early 1900s during the introduction of Western architecture to Korea. The results found in this study are as follows. First, in the case of the exterior of the building, despite being a Korean traditional building, the intention to pursue the Western style is very strong, and this trend can be found especially in bell towers planned as brick structures in front of the building and outer corridors on the side. Second, in the case of the Presbytery, it is faithful to the essential function of the space where worship takes place by having a spatial hierarchy that is clearly distinguished from the space of Nave. In particular, in the case of the space where the Presbytery is located, the Presbytery has no pillars in the center but two left and right pillars are planned, and a triumphal arch is formed between these pillars, preventing distractions from the vision toward the altar and separating the space between the Presbytery and the Nave. Third, in the case of Nave, rather than the formal demands of religious facilities, it is planned to be very faithful to the original function for worship. This is well reflected in the vertical axis of the interior plan of the building, the meaning of the column in the center, and the very practical functionality of the arrangement of the choir. Religious architecture is influenced by the ideas and cultures of that time and continues to develop as a result and adapt to solve them. The compromising Korean traditional Cathedral is our own valuable architectural asset that shows this trend very well.
