Gwangju Archdiocese Cathedral, completed during the period of liberation and turbulence, was built with some assistance from the U.S. military or with the efforts of the faithful, and there are a number of factors such as space directing by Aps, the development of a simplified bell tower, the appearance of a stone cathedral, the application of a quenset structure, and an increase in size. show special features The indented apse appears only after liberation, and is a characteristic that appears prominently in stone churches. The simplified form in which the bell was hung by raising the outer wall appeared in the early church shows a change in the composition with a porch in front. The stone church and the quanset-structured church only appeared after liberation and were built only in the 1950s.

The core idea of the critical regionalism could be summarized as a self-conscious synthesis between universal civilization and world culture. After World War Ⅱ, it has been applied to architecture for overcoming the problem of Industrial Capitalism and uniformity of 20th century Modern Architecture. Naturally, religious architecture cannot also be an exception in this cultural trend, thus we can also apply the critical regionalism to the Korean Catholic Church Architecture with the basic premise that the Traditional Western and Modern Style Church Architecture should be regarded as universal civilization, and the Traditional Korean Architecture and endemicity as one of world culture. In the context, this article attempts to analyze the regionality of Korean Modern Catholic Church Architecture constructed between the 19th century and 1980's, and how it has been differently transformed with the view of the critical regionalism. Its analysis will be carried out within three types; transformation of the Traditional Korean Architecture and the influence of Japanese Modern Architecture, representation of the Traditional Korean Architecture, and abstraction of the Traditional Korean Architecture with each advantages and disadvantages.
