Abstract
The purpose of this paper is to make clear the process of development of the architectures of churhes in the region of Nagasaki prefecture. I chose three elements for that purpose; the structure of the interior elevation, the structure of the roof (single or double) and the ratio of width of the nave to that of the aisle. It can be concluded that the architectures of churches continued being developed since the early period of Meiji and reached the peak in the half of Taisho era. Thereafter they were varied by the choices of the builders or the architects. I can also realize that the Japanese carpenters rather developed the architectures of churches from simple style to complex one than obtained the european architectural technics under the directions of the missionaries by means of taking the ancient Oura church as a model which had been built earliest in Nagasaki.
