In Jeju Island, Protestant churches have begun to be built mainly in coastal villages where people are crowded and traffic is convenient. The time for the establishment of a church and the construction of a church in the mid-mountain villages where access is difficult is late. The protestant church in Jeju Island rented a private house or warehouse when it was founded, and later built a church with a building in Choga(草家), Waga(瓦家) and stone. Especially, in the 1970s, cement brick or block church was built mainly, and in particular, the church began to be built with reinforced concrete. There are currently about 30 Protestant churches in Jeju Island, which were built in the 1950s and 1970s, and about 10 Catholic buildings(the Secondary Stations of Catholic church) at the same time remain. There is also a church that has a the reinforcing post for structural stability, resulting in a solid feel and a face-shaped split effect as well as a structural role. In the 1950s and 1970s, the Protestant Church in Jeju Island had the value of architectural history in connection with the dissemination of Protestants in the early Jeju.
