The Catholic Church of Korea has built the Church buildings focused on the liturgical space from the very beginning of the Church history. In the early days of its history, the Church had a liturgical space and a rectory, however, since the Second Vatican Council in 1962, it has expanded its space with the catechetical and the missionary space. In modern times, the building site has been getting smaller and the Church building has become a multipurpose one. This study seeks the characteristics of the Church area since 1990. It shows what is different in the Church architecture before and after 1990. The result is as follows. First, the Church becomes an high-rise and huge multipurpose building which has a basement. Second, when it becomes huge and high-rise, the 42.3% of the total space of the Church is used for a corridor, a hall and a basement garage. Third, the liturgical space is still plane and cross section after the Church became an multipurpose building. Fourth, the area for catechism and koinonia has been larger, but they are located in an basement level. The Church has been getting bigger year by year and the Church architecture considers an efficient use of the Church building, but still we need to plan more efficient space with its proper arrangement, minimizing additional spaces such as a corridor and a hall.
